win32u: Preserve result string from multiple WINE_IME_POST_UPDATE calls during ImeProcessKey.

In winemac.drv, there are multiple ime update calls occur during ImeProcessKey.
These multiple ime update calls need to be properly merged into ‘data->update’.
However, currently win32u/imm.c::post_ime_update() only keeps the last ime
update call.

Valid rules are:
 - The previous comp_str is discarded when the new ime update call occurs,
   so it is only valid if the last ime update call comp_str is not NULL.
 - The previous result_str is kept if the new ime update call result_str is NULL.
 - If both the previous and the new ime update call result_str are not NULL, then
   concatenate them.

Test key sequences are:
 - "Japanese Romanji" : 'nihongo-SPACE-n'
 - "Korean 2-Set Keyboard" : 'r-k-s-k'
 - "Korean 2-Set Keyboard" : 'r-k-1" or 'r-k-SPACE'
