LOG: [MLIR][CIR][NFCI] Split TestAliasAnalysis into its own library (#222174)

This is a target for the CIR alias analysis, and bringing in all of the
MLIRTestAnalysis is too heavy: it results in a significant increase in
CIR test size. This patch, plus a few little things, gets us ~850 edges
removed from the Clang Build (after Medhi's patches).

This also has CIR use it.
