  -----------
  [BOLT] DataAggregator support for binaries with multiple text segments (#92815)

When a binary has multiple text segments, the Size is computed as the
difference of the last address of these segments from the BaseAddress.
The base addresses of all text segments must be the same.

Introduces flag 'perf-script-events' for testing. It allows passing perf events
without BOLT having to parse them using 'perf script'. The flag is used to
pass a mock perf profile that has two memory mappings for a mock binary
that has two text segments. The size of the mapping is updated as this
change `parseMMapEvents` processes all text segments.
