Changelog:
https://git.linuxtv.org/libcamera.git/tag/?h=v0.7.1

libcamera is now using C++20. This minimal gcc version is increased
to gcc-10. This commit also removes the gcc >= 5 requirement for
the lc-compliance sub-option and the CXXFLAGS condition in the .mk
file. Those are no longer needed. The Config.in comments about the
required gcc version are also updated.

The Linux Kernel vimc driver became stricter on pixel format, after
upstream commit [1] (first included in Kernel v6.11). This commit
changes the RGB format to BGR, to request a supported format.
