patch 9.1.0423: getregionpos() wrong with blockwise mode and multibyte

Browse Source 
Problem:  getregionpos() wrong with blockwise mode and multibyte.
Solution: Use textcol and textlen instead of start_vcol and end_vcol.
          Handle coladd properly (zeertzjq).

Also remove unnecessary buflist_findnr() in add_regionpos_range(), as
getregionpos() has already switched buffer.

closes: #14805

"bufnum" is the buffer number.
"lnum" and "col" are the position in the buffer. The first
column is 1.
The "off" number is zero, unless 'virtualedit' is used. Then
it is the offset in screen columns from the start of the
character. E.g., a position within a <Tab> or after the last
character.
If the "off" number of a starting position is non-zero, it is
the offset in screen columns from the start of the character.
E.g., a position within a <Tab> or after the last character.
If the "off" number of an ending position is non-zero, it is
the character's number of cells included in the selection,
otherwise the whole character is included.
