Previously CMake was not aware of which headers files the generation of `gparams_register_modules.cpp` depended on. Consequently this could result in broken incremental builds if * Existing headers that declared module description/parameters change. * New headers are added that declare module description/parameters. * `.pyg` files that generate header files that declare module description/parameters change Now the `z3_add_component()` CMake function has been modifed so that * All header files that are generated from `.pyg` files are added as dependencies and are scanned from module description/parameter declarations. This implicit dependency of `gparams_register_modules.cpp` depending on other generated header files seems unnecessary complex. We should revisit this design decision once the Python/Makefile build system is deprecated. * The function now takes an optional `EXTRA_REGISTER_MODULE_HEADERS` argument which allows the headers that declare module description/paramters to be explicitly listed. With this information CMake will now regenerate `gparams_register_modules.cpp` correctly. This required the `mk_gparams_register_modules_internal()` function to be changed to take a list of header files rather than a list of component source directories. The two consumers (CMake and Python/Makefile build systems) of this function have been modified to work with this change. This partially fixes #1030.
