fix(ivy): ignore non-property bindings to inputs in template type checker (#33130)

Prior to this change, the template type checker would incorrectly bind
non-property bindings such as `[class.strong]`, `[style.color]` and
`[attr.enabled]` to directive inputs of the same name. This is
undesirable, as those bindings are never actually bound to the inputs at
runtime.

Fixes #32099
Fixes #32496
