What other libraries can we exclude from the CHPL_LLVM=bundled build

[jabraham17]

In recently found that we can force disable usage of libxml2 in the CHPL_LLVM=bundled build, as its optionally and only required by llvm-mt, a windows-only tool we don't use

See #27315

There may before libraries we can exclude that would improve the portability of CHPL_LLVM=bundled for users

Other cmake variables to consider

• LLVM_ENABLE_ZLIB
• LLVM_ENABLE_ZSTD
• LLVM_ENABLE_CURL
• LLVM_ENABLE_LIBEDIT (im pretty sure we should keep this one)
• LLVM_ENABLE_Z3_SOLVER
