feat(api): add nvim__redraw for more granular redrawing

Browse Source 
Experimental and subject to future changes.
Add a way to redraw certain elements that are not redrawn while Nvim is waiting
for input, or currently have no API to do so. This API covers all that can be
done with the :redraw* commands, in addition to the following new features:
- Immediately move the cursor to a (non-current) window.
- Target a specific window or buffer to mark for redraw.
- Mark a buffer range for redraw (replaces nvim__buf_redraw_range()).
- Redraw the 'statuscolumn'.

EXPERIMENTAL: this API may change in the future.
Instruct Nvim to redraw various components.
Parameters: ~
• {opts} Optional parameters.
• win: Target a specific |window-ID| as described below.
• buf: Target a specific buffer number as described below.
• flush: Update the screen with pending updates.
• valid: When present mark `win`, `buf`, or all windows for
redraw. When `true`, only redraw changed lines (useful for
decoration providers). When `false`, forcefully redraw.
• range: Redraw a range in `buf`, the buffer in `win` or the
current buffer (useful for decoration providers). Expects a
tuple `[first, last]` with the first and last line number of
the range, 0-based end-exclusive |api-indexing|.
• cursor: Immediately update cursor position on the screen in
`win` or the current window.
• statuscolumn: Redraw the 'statuscolumn' in `buf`, `win` or
all windows.
• statusline: Redraw the 'statusline' in `buf`, `win` or all
windows.
• winbar: Redraw the 'winbar' in `buf`, `win` or all windows.
• tabline: Redraw the 'tabline'.
