Enable globs on tasks otherwise fallback to default - fixes #88106 (#141230)

* use glob on tasks otherwise fallback to default

* add support for test commands also

* try to find one globbed task otherwise fallback to defaults

* - get relativePath (but fallback to absolute if outside of workspace)
- bring back json schema

* Refactor and reduce duplicate code

* remove glob, make isDefault a string or boolean

* update taskConfig

* - rebase
- type updates
- splitPerGroupType should check explicitly for true on isDefault
- hygiene check

* Remove task glob from API

* Task group DTO updates

* Make sure globs run ahead of default task if there's multiple globs matching

* Style and name changes

* More naming and code re-use

* Glob doesn't work when only 1 glob match
