patch 9.0.2186: LTCG compile error ARM64 for write_chars

Browse Source 
Problem:  LTCG compile error on Win/ARM64 for `write_chars()`
Solution: Explicitly initialise the storage to use data rather than BSS
          (Saleem Abdulrasool)

win32: add a workaround for a LTCG issue on Windows ARM64

It appears that the implicit initialisation which would push `g_coords`
into BSS causes an aliasing issue with LTCG on ARM64.  By explicitly
initialising the value, we use usual data storage but prevent the
aliasing.  This allows the console version of VIM to run on Windows
ARM64 again.

fixes:  #13453
closes: #13775
