efi/console: Move grub_console_set{colorstate,cursor} higher in the file

This is just a preparatory patch to move the functions higher in the file,
since these will be called by the grub_prepare_for_text_output() function
that will be introduced in a later patch.

The logic is unchanged by this patch. Functions definitions are just moved
to avoid a forward declaration in a later patch, keeping the code clean.
