  [BOLT] Add pre-parsed perf script support (#163785)

Implement the functionality to read and parse a pre-parsed perf-script
profile generated by perf2bolt's '--profile-format=perfscript' option.

The '-ps' option defines the perfscript input profile format. It requires
specifying the aggregation type ('--spe', '--ba') if it differs from
the default one ('brstack'). Note that the profile has to also be generated
using the exact same aggregation type.

Examples:
For ARM SPE:
1) $ perf2bolt BINARY -p perf.data -o test.text --spe --profile-format=perfscript
2) $ perf2bolt BINARY -o test.fdata -p test.text --spe -ps

For Brstack aggregation:
1) $ perf2bolt BINARY -p perf.data -o test.text --profile-format=perfscript
2) $ perf2bolt BINARY -o test.fdata -p test.text -ps
