command/pr: Support for only running specifically named test patterns (still with auto-detection)

Description

Currently changes to shared files with large amounts of unit testing introduces a large amount of testing noise when running via tctest:

It would be great if tctest provided a command option to control this behavior, such as --filter or --include-name-pattern or --include-file-pattern, beyond the hardcoded specifying the explicit test name patterns to match the auto-detected pattern. 👍 e.g.

$ tctest pr 13143 --include-name-pattern TestAcc
