feat(lsp): completion opts support custom item conversion (#30060)

Browse Source 
Problem: Some items of completion results include function signatures that can
cause the pum to be very long when a function has many params, because pum
scales with the longest word/abbr.

Solution: add custom covert function that can customise abbr to remove params.
