perf(hightlight): compute only bounds for non-blockwise highlights
Problem:
vim.hl.range() computes a segment for every selected line, then discards
all but the outer endpoints for characterwise and linewise highlights.
This makes highlighting large yanks and puts unnecessarily expensive.
Solution:
Use getregionpos() with bounds=true for these highlights. Also use bounds
in the keymap example that only needs the first and last selected lines.
