Add a new CMake target, qa_all, which builds all
tests, tools and their deps.
Then, when KICAD_BUILD_QA_TESTS is set OFF, remove tests
and tools from the ALL target, so `make all` doesn't include
these builds.
This means even when you turn the KICAD_BUILD_QA_TESTS option
off, you still have the option to:
* Build individual tests: `make qa_pcbnew`
* Build all tests: `make qa_all_tests`
* Build all tools: `make qa_all_tools`
* Build all QA executables: `make qa_all`
This also will provide a place to hang extra logic for test routine
wrangling (e.g. by CI tools)
Update the "Compiling KiCad" dev docs.
Also, CMakeModules .cmake files should not be excluded from git
