GDBus: add support for GVariant floats to helpers

Add support for G_VARIANT_TYPE_FLOAT to some helper functions.

We don't add support to the core serialiser because the sending side
already has a catch-all case for unsupported types (because of maybe
types) and the receiving side will never see floats on the wire.
