Ignore unused compiler options for "meson configure"

"meson setup" ignores unused compiler options, like "cpp_args" on a project without C++.

"meson configure" doesn't have the filtering from "set_default_options", so it fails with :
ERROR: Unknown options: "cpp_args"

So now unused compiler options (ie not in coredata.options) are no longer marked unknown.

Fixes: #11060
