keymap-x11: Don't update key types when adding key to keymap

Browse Source 
meta_keymap_x11_replace_keycode currently reports to the X server
that the key types data is changed when adding a key to the keymap.

It's not changed. The number of key types is the same, and none of
them are modified.

This has two bad side effects:

1) It sends all of the key types data into the request
2) It hits a bug in the X server leading to the request getting
rejected entirely.  See:

https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/761

Furthmore, the changed structure used to report to the X server
that the key types data is changed doesn't actually need to modified
at all in the function.  It's already prepped by libX11 with the
correct state for the changes mutter is doing when
XkbChangeTypesOfKey is called.

This commit addresses the above two problems by just removing the
lines causing the issues.
