Reland "Implicitly add necessary rules for Java reflections in any R8 mode."
PS1: same as original: https://r8-review.googlesource.com/c/r8/+/24260
PS4: rebase to a fix: https://r8-review.googlesource.com/c/r8/+/24424
PS6: fix remaining tests
PS7: not store -identifiernamestring rules for compat Proguard config
