This is similar to #185770 where it removes an exception-handling-related symbol from `compiler-rt` in favor of having definitions elsewhere. The compiler-rt library is linked into all shared objects, for example, which can result in duplicate definitions of a symbol where this tag wants to have one unique definition. The intention behind this commit is to defer the definition of this symbol to downstream libraries, such as the definition of `longjmp` itself. An example of this is WebAssembly/wasi-libc#772 where the responsibility of defining this symbol now lies with wasi-libc.

This commit adds a new CI builder for LLVM 22, distinct from preexisting builders using LLVM 20. This notably exposes a bug where setjmp/longjmp needed a fix because the method of definition of `__c_setjmp`, the tag used, changed in LLVM 22.
