Obviously `test-float-parse` is a tool like any other in `src/tools`.

Prior to stage 0 redesign, `test-float-parse` ran against in-tree std
but now it runs against beta std. `f16::FromStr` were only present in
in-tree std and not yet beta std, so apply `cfg(not(bootstrap))` gating
to unbrick `./x check --stage=0`.

This requires a fix to the subnormal test to cap the maximum allowed
value within the maximum mantissa.

Tell rustfmt to use the 2024 edition in ./x.py fmt
Most crates in this repo have been moved to the 2024 edition already. This also allows removing a rustfmt exclusion for a cg_clif test.

dec2flt: Clean up float parsing modules
This is the first portion of my work adding support for parsing and printing `f16`. Changes in `float.rs` replace the magic constants with expressions and add some use of generics to better support the new float types. Everything else is related to documentation or naming; there are no functional changes in this PR.
This can be reviewed by commit.

A lot of the magic constants can be turned into expressions. This
reduces some code duplication.
Additionally, add traits to make these operations fully generic. This
will make it easier to support `f16` and `f128`.

Currently, test case generators are launched in parallel and their test
cases also run in parallel, all within the same pool. I originally
implemented this with the assumption that there would be an advantage in
parallelizing the generators themselves, but this turns out to not
really have any benefit.
Simplify things by running generators in series while keeping their test
cases parallelized. This makes the code easier to follow, and there is
no longer a need for MPSC or multiprogress bars. Additionally, the UI
output can be made cleaner.

The existing implementation uses Python to launch a set of Rust-written
binaries. Unfortunately, this is currently broken; it seems that some
updates meant it no longer compiles.
There is also a problem that support for more float types (`f16`,
`f128`) would be difficult to add since this is very specialized to
`f32` and `f64`.
Because of these sortcomings, migrate to a version written in Rust. This
version should be significantly faster; test generators can execute in
parallel, and test cases are chunked and parallelized. This should also
resolve the preexisting "... the worker processes are leaked and stick
around forever" comment.
This change also introduces genericism over float types and properties,
meaning it will be much easier to extend support to newly added types.
`num::BigRational` is used in place of Python's fractions for
infinite-precision calculations.

This removes a dependency on fuchsia-cprng which doesn't have any
license info.

rust-lang/cargo#10910 starts emitting warning if resolver is not set
for 2021 edition package. We want to surpress the warning for now.

Implementation is based off fast-float-rust, with a few notable changes.
- Some unsafe methods have been removed.
- Safe methods with inherently unsafe functionality have been removed.
- All unsafe functionality is documented and provably safe.
- Extensive documentation has been added for simpler maintenance.
- Inline annotations on internal routines has been removed.
- Fixed Python errors in src/etc/test-float-parse/runtests.py.
- Updated test-float-parse to be a library, to avoid missing rand dependency.
- Added regression tests for #31109 and #31407 in core tests.
- Added regression tests for #31109 and #31407 in ui tests.
- Use the existing slice primitive to simplify shared dec2flt methods
- Remove Miri ignores from dec2flt, due to faster parsing times.
- resolves #85198
- resolves #85214
- resolves #85234
- fixes #31407
- fixes #31109
- fixes #53015
- resolves #68396
- closes https://github.com/aldanor/fast-float-rust/issues/15

Other terms are more inclusive and precise.

When using bash-specific features, scripts using env to call bash
are more convenient, as bash be installed in different places
according the OS.
Same applies for other languages' interpreters.

Running these tests takes hours, so they are not run by @bors.
