Update the value of ACC_VALUE and remove j.l.IdentityObject

[hangshao0]

1. Update the value of ACC_VALUE
2. remove ACC_PERMITS_VALUE
3. Add ACC_IDENTITY
4. remove IdentityObject
5. Update test code
6. Re-include PackageAnnotation tests which were excluded because of
   the injected j.l.IdentityObject.
7. OpenJDK ASM code is not updated for ACC_IDENTITY yet, it does not
   allow ACC_IDENTITY to be set. Exclude tests testGCRetransform and
   test_EXTENDED_HCR which failed on access flags check of ACC_IDENTITY

issue #15081, #12878

Because OpenJDK updated the value of ACC_VALUE, the valhalla builds are broken. This PR should unblock the valhalla builds.

@hangshao0 @tajila this broke at least internal DDR compilation. See /job_output.php?id=35316088
Pls fix quickly or revert.

I have a small change that should fix this. I'll launch an internal build to verify first.

#15150 should fix the internal build failure.
