  [lldb] Refactor GetFormatFromCString to always check for partial matches  (NFC) (#81018)

Refactors logic in `ParseInternal` that was previously calling
`GetFormatFromCString` twice, once with `partial_match_ok` set to false,
and the second time set to true.

With this change, lldb formats (ie `%@`, `%S`, etc) are checked first.
If a format is not one of those, then `GetFormatFromCString` is called
once, and now always checks for partial matches.

  -----------
  [X86] X86FixupVectorConstants - use explicit register bitwidth for the loaded vector instead of using constant pool bitwidth

Fixes #81136 - we might be loading from a constant pool entry wider than the destination register bitwidth, affecting the vextload scale calculation.

ConvertToBroadcastAVX512 doesn't yet set an explicit bitwidth (it will default to the constant pool bitwidth) due to difficulties in looking up the original register width through the fold tables, but as we only use rebuildSplatCst this shouldn't cause any miscompilations, although it might prevent folding to broadcast if only the lower bits match a splatable pattern.
