SCons: Add methods.get_version_info() method returning a Dict

This makes it possible to retrieve all relevant versioning info used to
generate `core/version_generated.gen.h` in the buildsystem.

Notably it makes the custom logic parsing the `GODOT_VERSION_STATUS`
environment variable to override status easy to reuse.

(cherry picked from commit d432fe38a9)
