  Log Message:
  -----------
  [TTI][TLI][AArch64] Support scalable immediates with isLegalAddImmediate (#84173)

Adds a second parameter (default to 0) to isLegalAddImmediate, to
represent a scalable immediate.

Extends the AArch64 implementation to match immediates based on what addvl and inc[h|w|d] support.
