Add new theme highlight keys, for setting the colour of the breakpoint
character and the current line at which execution has been paused at.
The two new keys are `ui.highlight.frameline` and `ui.debug.breakpoint`.
Highlight according to those keys, both the line at which debugging
is paused at and the breakpoint indicator.
Add an indicator for the current line at which execution is paused
at, themed by the `ui.debug.active` theme scope. Update various themes
to showcase how the new functionality works.
Better icons are dependent on #2869, and as such will be handled in the
future, once it lands.
Closes: #5952

Underline styles are mutally exclusive and overwrite each other.
Therefore implementing as an modifier lead to incorrect behaviour
when the underline style is overwritten.
For backwards compatability the "underline" modified is retained (but
deprecated). Instead the "underline_style" and "underline_color"
optios should be used to style underlines.
The cxterminfo crate has been used over popular alternatives
like `term` since it supports querying for extended capabilities
and also for it's small codebase size (which will make it easy
to inline it into helix in the future if required).
* Add markup support for all Base16 themes
* Fix rose_pine `markup.link.text` attribute misname
* Add basic default markup support for all themes
* Fix cursor change color on Base16 terminal and default
* Remove old markup monokai_pro support and fix Onedark `markup.link.text` attribute misname
* Remove old markup dracula support
* Add default color for cursor match
Not all terminals support dim, for those terminal that does not support
this (konsole, item2, wezterm), users cannot differentiate between match
and primary cursor. So set a color for this.
* Use alacritty dim color for match
