  [ARM/X86] Standardize the isEligibleForTailCallOptimization prototypes (#90688)

Pass in CallLoweringInfo (CLI) instead of passing in the various fields
directly. Also pass in CCState (CCInfo), which is computed in both the
caller and the callee for a minor efficiency saving. There may also be a
small correctness improvement for sibcalls with vectorcall, which has an
odd way of recomputing argument locations.

This is a step towards improving the handling of musttail on armv7,
which we have numerous issues filed about in our tracker.

I took inspiration for this from the RISCV tail call eligibility check,
which uses a similar prototype.
