Check if VarHandle access mode is supported.

This commit checks if a VarHandle access mode is supported. If not, an
UnsupportedOperationException is raised by calling the runtime to handle it.

I added the polymorphic intrinsics case in the IntrinsicSlowPath
code generation to handle all the eventual exceptions. For now,
none of the operations are actually compiled. If the slow path is
not called, the runtime handles the operation.

Bug: b/65872996
Test: art/test.py --host -r -t 712-varhandle-invocations --32
Test: art/test.py --host --all-compiler -r
