feat(signs)!: place higher-priority signs from the left #27781

Browse Source 
Problem:
Higher-priority signs may be hidden by lower-priority signs.

Solution:
Place higher-priority signs from the left.

Example:

    nvim_buf_set_extmark(0, ns, 0, -1, {sign_text='H', priority=1})
    nvim_buf_set_extmark(0, ns, 0, -1, {sign_text='W', priority=2})
    nvim_buf_set_extmark(0, ns, 0, -1, {sign_text='E', priority=3})

Before:

            |     |
          H | W E |
          ^ |     |
Not visible

After:

  |     |
  | E W | H
  |     | ^
          Not visible
