[PATCH] perf: test: Add support for testing JSON generated by perf data command

[Anup Sharma]

This commit adds support for testing the JSON output generated
by the perf data command's conversion to JSON functionality.
The test script now includes a validation step to ensure that
the resulting JSON file is contain valid data.

As a newcomer to this community, any feedback on the implementation
is highly appreciated.
