Add experimental support for 'strict-match' caching

Browse source 
By default, the action will attempt to restore a Gradle User Home
cache entry from a different set of matrix inputs (or a different Job entirely)
if an existing entry is not found for the current Job (including matrix inputs).

By specifying the experimental `gradle-home-cache-strict-match` parameter, a user
can avoid this fuzzy matching and ensure that a job execution starts with an
empty Gradle User Home if no entry from a prior execution is found.
