Add context parameters to SemanticDB synthetics (#23381)

## Fix #22936

Depends on scalameta/scalameta#4272 (for the generated SemanticsDB to be
consumable).

- Add `ApplyContextTree` from generated code, generated at
https://github.com/natsukagami/semanticdb-for-scala3/tree/apply-context-tree
- Use ApplyContextTree instead of ApplyTree for context parameter
applications
