patch 9.1.1138: cmdline completion for :hi is too simplistic
Problem: Existing cmdline completion for :highlight was barebone and
only completed the highlight group names.
Solution: Implement full completion for the highlight group arguments
such as guifg and cterm. If the user tries to complete
immediately after the '=' (e.g. `hi Normal guifg=<Tab>`), the
completion will fill in the existing value, similar to how
cmdline completion for options work (Yee Cheng Chin).
