[libcamera-ci] [RFC PATCH v1 3/3] Add job to run lc-compliance on the virtual pipeline handler

[Barnabás Pőcze]

Add a new job "lc-compliance:virtual" that uses the build artifacts
produced by the "build-test:debug" job to run lc-compliance in a
virtual machine on the "Virtual0" camera.

The `force_fallback_for=gtest` option is needed because `cpp_debustl`
makes ABI incompatible changes in the STL containers, so googletest
also needs to be compiled with these changes.
