RFR: 8356894: Adjust CreateSymbols to properly handle the newly added @jdk.internal.RequiresIdentity

[Jan Lahoda]

This patch builds on top of https://github.com/openjdk/jdk/pull/24746, and adds support for `@RequiresIdentity` to `--release`.

Important parts of the patch:
- `CreateSymbols` now keeps `RuntimeInvisibleTypeAnnotationsAttribute`/`RuntimeVisibleTypeAnnotationsAttribute` annotations
- for `ct.sym`, the `@RequiresIdentity` annotation is converted to a synthetic `@RequiresIdentity+Annotation`, as for other similar annotations.
- for parameters, there's a new flag that marks the parameter as "requires identity". The reason is that the other synthetic annotations on symbols used by `ct.sym`/`--release` are normally not added to the model, and hence invisible in the model. Flags are usually used instead of the synthetic annotations in javac. Using this new flag allows us to keep the behavior the same for the `@RequiresIdentity+Annotation`
- for type variables, the synthetic annotation is filtered out in the API method
