4178b954 - [SampleProfileMatcher] Flatten profiles loaded on demand (#184255)

[SampleProfileMatcher] Flatten profiles loaded on demand (#184255) Fix an issue that after loading top-level function from profile during CG matching, it's not flattened. This means the inlined callees of the loaded nested profile don't get their own entries in `FlattenedProfiles`, making them undiscoverable by subsequent CG matching steps.
