Refactor git-version.cmake to define the RPCS3_GIT_VERSION,
RPCS3_GIT_BRANCH, and RPCS3_GIT_TAG variables, and move the generation
of git-version.h to a function (gen_git_version).

While still in the project root:
1) `cd .. && mkdir rpcs3_build && cd rpcs3_build`
2) `cmake ../rpcs3/ && make GitVersion && make`
2) `cmake ../rpcs3/ && make`
3) Run RPCS3 with `./bin/rpcs3`
When using GDB, configure it to ignore SIGSEGV signal (`handle SIGSEGV nostop noprint`).
