When we reconfigure, `configure_file()` is called again, and `*.gresource.xml` files are regenerated, which causes many (all?) binaries to be relinked. Now we only write those out if the contents actually changed (or if the output didn't already exist). This is exactly what Meson already does with `configure_file()` when `command:` is not used. While we're at it, also do the same for `gen-c-array.py` and `gentypefuncs.py` for completeness. Now even if the input to those changes, re-building of those custom targets may not result in relinking if the outputted C files have the same contents.
