[OE-core][PATCH 2/4] spdx 3.0: Map gitsm URI to git

[Joshua Watt <jpewhacker@gmail.com>]

"gitsm" is not a recognized URI protocol (outside of bitbake), so map it
to "git" when writing. This should be OK since we report all of the
submodule source code (if enabled), and it's still possible for 3rd
party analyzers to determine that submodules are in use by looking at
.gitmodules.

The code to do the mapping is moved to a common location so it covers
SPDX 2.2 also

[YOCTO #15582]
