vim-patch:8.2.4559: getmousepos() returns the screen column

Browse Source 
Problem:    getmousepos() returns the screen column. (Ernie Rael)
Solution:   Return the text column, as documented.
533870a985

Re-introduce vcol2col, which was removed in 71b1f4e for being unused.
Move it to mouse.c (like in v8.1.2062, which hasn't been ported yet).
