What changed in this PR
Converts the shared CodeQL utility and threat-model data extensions from YAML to JSON for faster loading in CodeQL CLI 2.27.3 while preserving the existing extension data.
Changes:
- Registers JSON data extensions in the shared utility and threat-model pack manifests.
- Replaces the default alert-filter YAML extension with JSON.
- Replaces the threat-model grouping and supported-threat-model YAML extensions with JSON equivalents.

CodeQL CLI 2.27.3 supports JSON data extensions (aka MaD models), and can load them significantly faster than YAML. This PR converts those in the
sharedpacks.To verify successful conversion, I cherry-picked this commit onto #23059, which has a temporary test that enumerates all tuples from data extensions. The test still passes after conversion.
