LSP: enable using different highlighting rules for LSP signs (#12176)

Browse Source 
This commit creates 4 new highlight groups:
- LspDiagnosticsErrorSign
- LspDiagnosticsWarningSign
- LspDiagnosticsInformationSign
- LspDiagnosticsHintSign

These highlight groups are linked to their corresponding LspDiagnostics
highlight groups by default.

This lets users choose a different color for their sign columns and
virtualtext diagnostics.
