ci: Enable opt-dist for dist-aarch64-linux builds
Move the CI dist-aarch64-linux job to an aarch64 runner and enable optimised dist builds with the opt-dist pipeline.
For the time being, disable bolt on aarch64 due to upstream bolt bugs.

Move shared helper scripts used by Docker builds under docker/scripts.

Move the dist-aarch64-linux CI job to an aarch64 runner instead of
cross-compiling it from an x86 one. This will make it possible to
perform optimisations such as LTO, PGO and BOLT later on.

CI: Add LTO support to clang in dist-x86_64-linux
After https://github.com/rust-lang/cc-rs/pull/1279, we attempt to pass `-flto=thin` to clang. In `dist-x86_64-linux`, we don't build clang with the `LLVMgold.so` library so this fails. This attempts to resolve this
First, pass the binutils plugin include directory to Clang, [which will build the library](https://github.com/llvm/llvm-project/blob/2d6d723a85c2d007b0359c206d66cd2e5a9f00e1/llvm/docs/GoldPlugin.rst#how-to-build-it)
Second, this library depends on the *version of libstdc++ that we built* specifically. However, despite both the RPATH and LD_LIBRARY_PATH pointing to `/rustroot/lib`, we incorrectly resolve to the system libstdc++, which doesn't load.
```
# LD_DEBUG=libs,files
2219: file=libstdc++.so.6 [0]; needed by /rustroot/bin/../lib/LLVMgold.so [0]
2219: find library=libstdc++.so.6 [0]; searching
2219: search path=/rustroot/bin/../lib/../lib (RPATH from file /rustroot/bin/../lib/LLVMgold.so)
2219: trying file=/rustroot/bin/../lib/../lib/libstdc++.so.6
2219: search path=/usr/lib64/tls:/usr/lib64 (system search path)
2219: trying file=/usr/lib64/tls/libstdc++.so.6
2219: trying file=/usr/lib64/libstdc++.so.6
```
Using `LD_PRELOAD` causes it to correctly load the library
I think this is probably not the most maintainable way to do this, so opening to see if this is desired and if there's a better way of doing this

Bump Fuchsia toolchain for testing
This updates the Fuchsia SDK used to test rust on Fuchsia to 26.20241211.7.1, and clang to the development version 20 from 388d7f144880dcd85ff31f06793304405a9f44b6.
```@steven807``` asked me to take over the PR. Since I don't have commit access to his repo, I just cherry picked his patch here.

Promote powerpc64le-unknown-linux-musl to tier 2 with host tools
MCP: https://github.com/rust-lang/compiler-team/issues/803
I'm using crosstool-ng for building a toolchain because GCC 9 from `musl-toolchain.sh` has float ABI issues (?) and can't compile LLVM, and writing a crosstool-ng config for a target feels less hacky than yet another target specific shell script. I also defined a kernel version, since there wasn't one specified before. If a lower version is desired, just let me know. I also tried to match the rust configure args with the loongarch64 musl tier 2 target.
The resulting compiler works fine, built with `DEPLOY=1 ./src/ci/docker/run.sh dist-powerpc64le-linux` and tested on Alpine Linux in a VM and on a bare metal POWER8 machine:
