[bug] Templates via classpath (#5164)

Browse Source 
* Fixes issue with templates loading via classpath

The templating engines were originally written to load templates via the
classpath, but this functionality was blocked by file-only checks
further up the stack. This loosens those file-only checks, allowing
files and relatively imported files to be included via classpath.

* [docs] Add details about classpath-level templates

* [feat][maven] templateResourcePath for template on classpath
  - NOTE templateResourcePath is not needed for gradle, as it accepts
    a string for the target template directory, which supports classpath
