Extreme testcase:
```lua
vim.fn.setline(1, 'foobar')
local ns = vim.api.nvim_create_namespace('')
for _ = 1, 100000 do
vim.api.nvim_buf_set_extmark(0, ns, 0, 3, {})
end
local start_time = vim.loop.hrtime()
vim.fn.virtcol('$')
local stop_time = vim.loop.hrtime()
print(stop_time - start_time)
```

Get rid of the weird attr_pri dance which always seemed like a kludge:
if (!attr_pri) {
wlv.char_attr = hl_combine_attr(wlv.char_attr, extmark_attr);
} else {
wlv.char_attr = hl_combine_attr(extmark_attr, wlv.char_attr);
}
Instead combine extmark attrs with (old-skool) syntax attrs in a consistent way and then combine that with attr_pri and the rest in an _unified_ code path

Problem: After exiting Insert mode spelling is not checked in the next
