RFR: 8320360: ClassFile.parse: Some defect class files cause unexpected exceptions to be thrown

[Adam Sotona]

ClassFile API throws `IndexOutOfBoundsException` when classfile structure is corrupted so the parser attempts to read beyond the classfile bounds.
General contract is that only `IllegalArgumentException` or its subclasses is expected when parser fails.
This patch wraps `IndexOutOfBoundsExceptions` thrown from all `ClassReaderImpl.buffer` manipulations into an  `IllegalArgumentException("Reading beyond classfile bounds", iOOBECause)`.
Relevant tests are added.

Please review.

Thanks,
Adam
