Use a stub stdlib.h when compiling for UEFI targets
...
int_util.c includes stdlib.h if `_WIN32` is defined. When compiling
the UEFI targets with clang they are treated as Windows targets (e.g. if
the Rust target is x86_64-unknown-uefi, the clang target is
x86_64-unknown-windows-gnu). So stdlib.h gets included, even though we
are compilling with `-ffreestanding` and don't want stdlib.h to be
used. That file may not be present, or an incompatible version might be
installed leading to typedef redefinition errors.
The contents of stdlib.h aren't actually needed for these targets anyway
(due to `__STDC_HOSTED__` being 0), so create a minimal stdlib.h in
`build.rs` when `target_os == uefi` and add it to the include path.

Skip assembly implementations on the UEFI targets
...
The UEFI targets link with `/SAFESEH`. That requires that objects have a
symbol called [`@feat.00`]. Clang adds that symbol for COFF targets if
the input is a C file, but not if the input is an ASM file. That doesn't
prevent compiler_builtins or rustc from building, but using the
resulting rustc to compile something that references one of the objects
lacking `@feat.00` will result in a linker error.
Fix by removing all the `.S` implementations when `target_os == uefi`.
[`@feat.00`]: https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#the-sxdata-section

Enable unadjusted_on_win64 for UEFI in some cases
...
The conversion functions from i128/u128 to f32/f64 have the
`unadjusted_on_win64` attribute, but it is disabled starting with
LLVM14. This seems to be the correct thing to do for Win64, but for some
reason x86_64-unknown-uefi is different, despite generally using the
same ABI as Win64.
