Problem: not possible to style popup borders globally
Solution: Add the 'pumborder' option (Girish Palya)
This commit introduces a new global option, 'pumborder' ('pb'), that
allows users to define borders and optional decorations for the
completion popup menu.
```
Defines a border and optional decorations for the popup menu in
completion. The value is a comma-separated list of keywords.
Border styles (at most one):
"single"singleuse thin box-drawing characters
"double"doubleuse double-line box-drawing characters
"round"rounduse rounded corners
"ascii"asciiuse ASCII characters (-, |, +)
"custom:XXXXXXXX"
use eight characters given after "custom:",
in order: top, right, bottom, left,
topleft, topright, botright, botleft
Additional flags:
"margin"marginadds one-cell spacing inside the left and right border
"shadow"shadowdraws a shadow at the right and bottom edges
Highlight groups:
|hl-PmenuBorder|hl-PmenuBorderused for the border characters
|hl-PmenuShadow|hl-PmenuShadowused for the shadow
Examples: >
:set pumborder=single
:set pumborder=double,margin,shadow
:set pumborder=custom:─│─│┌┐┘└,shadow
Border styles using box-drawing characters ("single", "double",
"round") are only available when |'encoding'| is "utf-8" and
|'ambiwidth'| is "single". "margin" requires a border style.

Problem: MS-Windows: not possible to highlight the title bar
Solution: Make the title/caption bar configurable by introducing the
'go-C' option value which allows to highlight it using the
TitleBar and TitleBarNC highlighting groups (Mao-Yining).
Introduce titlebar color customization for Windows 11 GUI through
highlight groups and new 'guioptions' flag:
- Add 'C' flag to enable titlebar color customization (opt-in)
- New highlight groups: TitleBar (active) and TitleBarNC (inactive)
- Uses DWMWA_CAPTION_COLOR and DWMWA_TEXT_COLOR DWM attributes
- Dynamically loads dwmapi.dll for Windows 11 compatibility
- Defaults to system colors when set to NONE or feature disabled

When adding new highlight groups, one needs to make sure to also add a
"default link NewHlGroup ExistingHlGroup" in highlight.c code, so that
when resetting a color scheme the old color won't be left behind.
So add a Makefile in the 'ci' directory that verifies that all
documented '*hl-<groupname>' from the documentation are either reflected
in the source code, or belong to a list of 'known to be ignored'
highlight groups and let that check run as part of the CI test suite.
