version-check should attempt to read F´ version if ran in a project

F´ Version	v3.5

Feature Description

fprime-util version-check was built so that it doesn't require to be in a project to be ran. It simply prints out a bunch of things, without trying to load the build/project.
This has the downside that we can't read the F´ version, since this requires to load project information. But it does have the advantage of being runnable anywhere, and not just within an fprime project.

It would be nice if we could read the F´ version nonetheless. We could either:

• attempt to load the project/build-cache, if that doesn't work, skip the load and don't print F´ version
• more rudimentary, simply look into ./fprime ./lib/fprime and other common locations if there exists a .git repo

You could use git submodule to list out submodules to select the proper fprime submodule. Something like:

$ git submodule foreach 'git remote get-url origin && git describe --tags --always'
Entering 'fprime'
git@github.com:nasa/fprime.git
v3.4.3-24-gff16e1821

Thanks @Kronos3 - that does seem like the ideal solution here, so we can still skip the build-loading step.
