[CIR] Add additional frontend actions (#127249)

Add frontend actions to support emitting assembly, bitcode, and object
files when compiling with ClangIR. This change also correctly sets and
propagates the target triple in the MLIR and LLVM modules, which was a
necessary prerequisite for emitting assembly and object files.
