zeertzjq e51f217be7 vim-patch:9.2.0223: Option handling for key:value suboptions is limited (#38426) 
Problem:  Option handling for key:value suboptions is limited
Solution: Improve :set+=, :set-= and :set^= for options that use
          "key:value" pairs (Hirohito Higashi)

For comma-separated options with P_COLON (e.g., diffopt, listchars,
fillchars), :set += -= ^= now processes each comma-separated item
individually instead of treating the whole value as a single string.

For :set += and :set ^=:
- A "key:value" item where the key already exists with a different value:
  the old item is replaced.
- An exact duplicate item is left unchanged.
- A new item is appended (+=) or prepended (^=).

For :set -=:
- A "key:value" or "key:" item removes by key match regardless of value.
- A non-colon item removes by exact match.

This also handles multiple non-colon items (e.g., :set
diffopt-=filler,internal) by processing each item individually, making
the behavior order-independent.

Previously, :set += simply appended the value, causing duplicate keys to
accumulate.

fixes:  vim/vim#18495
closes: vim/vim#19783
