refactor(compiler-cli): Adjust output of TCB to support TemplateTypeChecker Symbol retrieval (#38618)

The statements generated in the TCB are optimized for performance and producing diagnostics.
These optimizations can result in generating a TCB that does not have all the information
needed by the `TemplateTypeChecker` for retrieving `Symbol`s. For example, as an optimization,
the TCB will not generate variable declaration statements for directives that have no
references, inputs, or outputs. However, the `TemplateTypeChecker` always needs these
statements to be present in order to provide `ts.Symbol`s and `ts.Type`s for the directives.

This commit adds logic to the TCB generation to ensure the required
information is available in a form that the `TemplateTypeChecker` can
consume. It also adds an option to the `NgCompiler` that makes this
generation configurable.
