Moves the logic for generating type check blocks into the compiler since it isn't coupled to TypeScript anymore.
Note: the tests haven't been moved over, because they depend on the environment that's currently in `compiler-cli` and it still has some dependencies on TypeScript.
Decouple `SymbolBuilder` from the full `BoundTarget` interface by introducing a purpose-built `SymbolBoundTarget` interface containing only the 4 methods required for symbol resolution. This eliminates the need for the large, pass-through `BoundTargetAdapter` and further isolates `SymbolBuilder` from compiler-internal implementation details.
Also minimize `TypeCheckableDirectiveMetaAdapter` by redefining `SymbolDirectiveMeta` to not extend `DirectiveMeta`, exposing only the properties actually used by `SymbolBuilder`.
Removed dead code `getDirectiveMeta` in `template_symbol_builder.ts` which was unused.
These changes improve maintainability and ensure a cleaner architecture by strictly defining the boundaries of what `SymbolBuilder` needs from the rest of the system.
By limiting the required inputs to only what's necessary for the implementation, we make it easier to re-use
the implementation between different compiler architectures
Moves the `ClassPropertyMapping` into the compiler, rather than having to pass around the limited `InputOutputPropertySet` interface that is only implemented by `ClassPropertyMapping`.
Currently the `OutOfBandDiagnosticRecorder` is tied to producing TypeScript diagnostics, however some of our use cases might call for a different form.
These changes decouple the recorder from TypeScript and make the diagnostic type generic.
