fix(ivy): include directive base class metadata when generating TCBs (#29698)

Browse Source 
Previously the template type-checking code only considered the metadata of
directive classes actually referenced in the template. If those directives
had base classes, any inputs/outputs/etc of the base classes were not
tracked when generating the TCB. This resulted in bindings to those inputs
being incorrectly attributed to the host component or element.

This commit uses the new metadata package to follow directive inheritance
chains and use the full metadata for a directive for TCB generation.

Testing strategy: Template type-checking tests included.
