build/meson: support running codegen

also removed -M during the test_fib.c codegen:

902cc2c ("Add native module support on Windows")
switched examples to dynamic import() instead of static import statement
and the lookup was deferred to runtime, thus we don't need to hint qjsc
this is a declared module and exclude it from bundling.
