gopls/internal/lsp/source: highlight deprecated symbols

This utilizes the code copied from honnef.co/tools/staticcheck.
Unlike staticcheck.CheckDeprecated that assumes analyzers with
`-go` flag specifying the target go version and utilizes structured
knowledge of stdlib deprecated symbols, this analyzer depends
on the facts and surfaces the deprecation notices as written in
the comments. We also simplified implementation during review.

Gopls turns this analyzer's reports to Hint/Deprecated diagnostics.
Editors like VS Code strike out the marked symbols but don't
surface them in the PROBLEMS panel.

Fixes golang/go#40447
