This adds support for the 'go install' case, where we link against the
system LLVM (Homebrew, Linux distro version, etc). This does not have an
effect on `make`, which still uses LLVM 19 for now.
The main reason for doing this is because newer distros like Fedora 42
and Homebrew have switched to LLVM 20, so switching to this newer
version helps those people. (I'm one of those people, I'm on Fedora 42).
There are two small changes for WebAssembly included:
* nontrapping-fptoint was enabled in the wasmbuiltin library used for
wasm-unknown. This matches wasm-unknown which already had this
enabled, so it doesn't add any new instructions.
* bulk-memory was enabled in wasi-libc. This was previously enabled in
all the other WebAssembly targets (wasm, wasip1, wasip2) so this
does't add any new instructions. I think it was also enabled in the
wasi-libc build before
#4820 but I don't know for
sure.

This adds support for the 'go install' case, where we link against the system LLVM (Homebrew, Linux distro version, etc). This does not have an effect on
make, which still uses LLVM 19 for now until the Espressif Xtensa fork is updated.The main reason for doing this is because newer distros like Fedora 42 and Homebrew have switched to LLVM 20, so switching to this newer version helps those people. (I'm one of those people, I'm on Fedora 42).
Somewhat surprisingly, it seems like everything just works with this newer LLVM version.
