Adjust Makefile to generate version.php, refactor

[PVince81]

Description

Makefile now adds OC_Edition in version.php.
Refactored Makefile with functions used by both the regular and QA
build, for cleaning up unwanted files and updating version.php.

Related Issue

None

Motivation and Context

Remove the need to touch version.php in the internal release script.
Reuse some logic.

How Has This Been Tested?

Run make clean && make dist and check generated version.php. Check that test folders and git folders were removed as well.
Run make clean && make dist-qa and check generated version.php. Check that test folders are still there but ".git*" folders are gone.
