py/mkrules.cmake: Support passing CFLAGS_EXTRA in environment variable.
This works similarly to the existing support in "bare metal" make ports,
with the caveat that CMake will only set this value on a clean build and
will reuse the previous value otherwise.
This is slightly different to the CMake built-in support for CFLAGS,
as this variable is used when evaluating source files for qstr
generation, etc.
This work was funded through GitHub Sponsors.
