Expose `compiler-builtins-weak-intrinsics` feature for `-Zbuild-std`
This was added in rust-lang/compiler-builtins#526 to force all compiler-builtins intrinsics to use weak linkage.
STD support for PSVita
This PR adds std support for `armv7-sony-vita-newlibeabihf` target.
The work here is fairly similar to #95897, just for a different target platform.
This depends on the following pull requests:
rust-lang/backtrace-rs#523rust-lang/libc#3209
Report allocation errors as panics
OOM is now reported as a panic but with a custom payload type (`AllocErrorPanicPayload`) which holds the layout that was passed to `handle_alloc_error`.
This should be review one commit at a time:
- The first commit adds `AllocErrorPanicPayload` and changes allocation errors to always be reported as panics.
- The second commit removes `#[alloc_error_handler]` and the `alloc_error_hook` API.

Add support for QNX Neutrino to standard library
This change:
- adds standard library support for QNX Neutrino (7.1).
- upgrades `libc` to version `0.2.139` which supports QNX Neutrino
`@gh-tr`
⚠️ Backtraces on QNX require https://github.com/rust-lang/backtrace-rs/pull/507 which is not yet merged! (But everything else works without these changes) ⚠️
Tested mainly with a x86_64 virtual machine (see qnx-nto.md) and partially with an aarch64 hardware (some tests fail due to constrained resources).
RustHermit publishs a new kernel interface and supports
a common BSD socket layer. By supporting this interface,
the implementation can be harmonized to other operating systems.
To realize this socket layer, the handling of file descriptors
is also harmonized to other operating systems.
This was originally a part of https://github.com/rust-lang/rust/pull/100316.
However, extracting it to a seperate PR should help with any extra
testing that might be needed.

RustHermit and HermitCore is able to run on aarch64 and x86_64.
In the future these operating systems will also support RISC-V.
Consequently, the dependency to a specific target should be removed.
Building hermit-abi fails if the architecture isn't supported.
Bump libc and fix remove_dir_all on Fuchsia after CVE fix
With the previous `is_dir` impl, we would attempt to unlink
a directory in the None branch, but Fuchsia supports returning
ENOTEMPTY from unlinkat() without the AT_REMOVEDIR flag because
we don't currently differentiate unlinking files and directories
by default.
On the Fuchsia side I've opened https://fxbug.dev/92273 to discuss
whether this is the correct behavior, but it doesn't seem like
addressing the error code is necessary to make our tests happy.
Depends on https://github.com/rust-lang/libc/pull/2654 since we
apparently haven't needed to reference DT_UNKNOWN before this.

Updates std's libc crate to include DT_UNKNOWN for Fuchsia.
