test(ivy): mark jit_summaries_integration_spec as obsolete in Ivy (#28027)
These tests validate the ability of the View Engine TestBed to consume summary metadata, a mechanism which allows the TestBed to use AOT-compiled components & directives in tests. It achieves this through two operations which are independently obsolete in Ivy: 1. It injects CompileMetadataResolver, a View Engine specific compiler internal class which extracts global analysis metadata from classes, and uses it to construct summary metadata. This happens in a beforeEach() block which calls createSummaries(). 2. It uses TestBed.initTestEnvironment to pass summary metadata to the TestBed itself. Any such metadata is ignored in Ivy. Operation #1 makes it impossible to run these tests under Ivy, as the CompileMetadataResolver is not available with an Ivy compiler. Ivy itself does not rely on summary data, and the R3TestBed can depend directly on AOT compiled components without it. Thus, the spirit of thes tests is obsolete in an Ivy world.
