Remove MERGE_ALT_FORM merge mode
The mode comes from the "alternate" keyword, which is unused in xkeyboard-config and mostly undocumented. Its purpose is to allow to assign the same key name to multiple key codes, which is not allowed otherwise (and doesn't make much sense). The xkblib specification implies that this was part of the overlay functionality, which we also no longer support. If we do encounter this keyword, we just treat it as MERGE_DEFAULT. The keycodes.c code will detect a collision and will ignore all but the first key code (and the error count is not incremented). Some peripheral code is also removed as a result.
