fix(ivy): prevent unknown element check for AOT-compiled components (#34024)

Prior to this commit, the unknown element can happen twice for AOT-compiled components: once during compilation and once again at runtime. Due to the fact that `schemas` information is not present on Component and NgModule defs after AOT compilation, the second check (at runtime) may fail, even though the same check was successful at compile time. This commit updates the code to avoid the second check for AOT-compiled components by checking whether `schemas` information is present in a logic that executes the unknown element check.
