Update Let's Encrypt ROOT CA certificate in dist-(i686|x86_64)-linux docker images
The DST Root CA X3 used by Let's Encrypt has expired ([Let's Encrypt announcement](https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/)). This patch installs the new root certificate (ISRG Root X1) and disables the old one. Disabling the old one is necessary because otherwise curl still fails to download from servers with Let's Encrypt certs even though they are cross-signed.
Fixes #89484.

This skips bumping Windows sccache because we run into compilation failures when
doing so (-m32 not supported by clang-cl?). Not clear on cause, but seems
easiest to just hold back.
This should avoid PGO-related failures encountered on Linux, and more broadly
seems like a good idea on other platforms as well (though it is likely not
necessary right this moment).

This shows up to 5% less instruction counts on multiple benchmarks, and up to
19% wins on the -j1 wall times for rustc self-compilation.
We can afford to spend the extra cycles building LLVM essentially once more for
the x86_64-unknown-linux-gnu CI build today. The builder finishes in around 50
minutes on average, and this adds just 10 more minutes. Given the sizeable
improvements in compiler performance, this is definitely worth it.

Remove git fetch from CI
https://github.com/rust-lang/rust/pull/86623 added a call to `git fetch`, which is problematic for releases.

This is needed to handle R_X86_64_REX_GOTPCRELX relocations.

The LLD + ThinLTO __morestack bug has been fixed in 12.0.1, so
we can now update our clang version. This also means that we no
longer need to build Python 2.

Use HTTPS links where possible
While looking at #86583, I wondered how many other (insecure) HTTP links were in `rustc`. This changes most other `http` links to `https`. While most of the links are in comments or documentation, there are a few other HTTP links that are used by CI that are changed to HTTPS.
Notes:
- I didn't change any to or in licences
- Some links don't support HTTPS :(
- Some `http` links were dead, in those cases I upgraded them to their new places (all of which used HTTPS)

This is needed as they are built on a long-outdated Debian version. :(

During the 1.52 release process we had to deal with some commits that
passed the test suite on the nightly branch but failed on the beta or
stable branch. In that case it was due to some UI tests including the
channel name in the output, but other changes might also be dependent on
the channel.
This commit adds a new CI job that runs the Linux x86_64 test suite with
the stable branch, ensuring nightly changes also work as stable.

Build crtbegin.o/crtend.o from source code
Build crtbengin.o/crtend.o from source code instead of copying from gcc.
The crtbegin and crtend implementation from llvm don't need `crtbeginS.o` for PIC. `crtbegin{,S,T}.o` is unified into one generic `crtbegin.o`. See the comments in https://reviews.llvm.org/D28791#1419436 and https://reviews.llvm.org/D28791#1420914

Add eslint checks to CI
It also allowed me to fix some potential issues that went unnoticed. Having this process automated will hopefully prevent us to add more errors. :)

Bring back `x86_64-sun-solaris` target to rustup
Change #82216 removed now deprecated target `x86_64-sun-solaris` from CI, thus making it no longer possible to use `$ rustup target add x86_64-sun-solaris` to install given target (see #85098 for details). Since there should be a period of time between the deprecation and removal, this PR brings it back (while keeping the new one as well).
Please, correct me if I am wrong; my assumption that these Docker scripts are being used to build artifacts later used by `rustup` might be incorrect.
Closes #85098.

This commit implements the idea of a new ABI for the WebAssembly target,
one called `"wasm"`. This ABI is entirely of my own invention
and has no current precedent, but I think that the addition of this ABI
might help solve a number of issues with the WebAssembly targets.
When `wasm32-unknown-unknown` was first added to Rust I naively
"implemented an abi" for the target. I then went to write `wasm-bindgen`
which accidentally relied on details of this ABI. Turns out the ABI
definition didn't match C, which is causing issues for C/Rust interop.
Currently the compiler has a "wasm32 bindgen compat" ABI which is the
original implementation I added, and it's purely there for, well,
`wasm-bindgen`.
Another issue with the WebAssembly target is that it's not clear to me
when and if the default C ABI will change to account for WebAssembly's
multi-value feature (a feature that allows functions to return multiple
values). Even if this does happen, though, it seems like the C ABI will
be guided based on the performance of WebAssembly code and will likely
not match even what the current wasm-bindgen-compat ABI is today. This
leaves a hole in Rust's expressivity in binding WebAssembly where given
a particular import type, Rust may not be able to import that signature
with an updated C ABI for multi-value.
To fix these issues I had the idea of a new ABI for WebAssembly, one
called `wasm`. The definition of this ABI is "what you write
maps straight to wasm". The goal here is that whatever you write down in
the parameter list or in the return values goes straight into the
function's signature in the WebAssembly file. This special ABI is for
intentionally matching the ABI of an imported function from the
environment or exporting a function with the right signature.
With the addition of a new ABI, this enables rustc to:
* Eventually remove the "wasm-bindgen compat hack". Once this
ABI is stable wasm-bindgen can switch to using it everywhere.
Afterwards the wasm32-unknown-unknown target can have its default ABI
updated to match C.
* Expose the ability to precisely match an ABI signature for a
WebAssembly function, regardless of what the C ABI that clang chooses
turns out to be.
* Continue to evolve the definition of the default C ABI to match what
clang does on all targets, since the purpose of that ABI will be
explicitly matching C rather than generating particular function
imports/exports.
Naturally this is implemented as an unstable feature initially, but it
would be nice for this to get stabilized (if it works) in the near-ish
future to remove the wasm32-unknown-unknown incompatibility with the C
ABI. Doing this, however, requires the feature to be on stable because
wasm-bindgen works with stable Rust.
