  -----------
  [llvm-gsymutil] Add support for merged functions lookup differentiation (#122409)

This update introduces the ability to filter merged functions during
lookups based on regex patterns derived from call site information in a
previous call to `llvm-gsymutil`. The regex patterns, extracted from
call sites, can then be passed to subsequent calls using the
`--merged-functions-filter` option along with `--merged-functions` and
`--address` (or `--addresses-from-stdin`). This allows for precise
filtering of functions during lookups, giving accurate results for call
stacks that contain merged functions.
