CLS: support more end marker types

[jabraham17]

The language server currently adds inlay hints to the ends of interesting blocks, however there are a few more block types it should support.

• select/when
  • I have actively seen comments for this used in code, this will directly support users
• try/catch
  • for completeness
• if/else
  • this one is funky, as a common coding style is to attach else to the trailing brace (} else)
