[jdk21u-dev] RFR: 8324641: [IR Framework] Add Setup method to provide custom arguments and set fields

[Aleksey Shipilev]

Improves IR Framework, allows backporting IR Tests without modifications. Applies nearly cleanly, except the hunk in `compiler/c2/irTests/TestTestRemovalPeephole.java`, since this file does not exist in JDK 21.

Additional testing:
 - [x] Grep `@Arguments` yields no unfixed cases in test suite
 - [x] MacOS AArch64 server fastdebug, `testlibrary_tests/ir_framework compiler/c2/irTests`
 - [ ]  Linux AArch64 server release, `testlibrary_tests/ir_framework compiler/c2/irTests`
 - [ ]  Linux AArch64 server fastdebug, `testlibrary_tests/ir_framework compiler/c2/irTests`
