LOG: [KeyInstr] Enable Key Instructions support in LLVM (#144324)

Set LLVM_EXPERIMENTAL_KEY_INSTRUCTIONS=ON by default. This enables
support for Key Instructions in LLVM by default, it does not enable the
feature by default.

This does have an affect on compile time, which looks to have mostly
been "paid for" (if that argument stands) by my PR #143399.
