fix(ivy): reflect animations field directly into the output definition (#26322)

The 'animations' field of @Component metadata should be copied directly
into the ngComponentDef for that component and should not pass through
static resolution.

Previously the animations array was statically resolved and then the
values were translated back when generating ngComponentDef.
