internal/lsp/source: support some fzf-like tokens in symbol matching

It's useful to be able to switch between case sensitive, case
insensitive, and fuzzy matching for symbol without having to reload
gopls. FZF has some nice syntax for this:
  https://github.com/junegunn/fzf#search-syntax

Adopt a subset of this syntax for our symbol search:
  ' for exact matching
  ^ for prefix matching
  $ for suffix matching

It would be straightforward to also support inversion, using
'!', but I deemed this unnecessary.

I think we should adopt this, since none of these symbols conflicts with
Go identifiers, or (AFAIK) with special syntax in major LSP clients.
