[cDAC] Implement `IXCLRDataStackWalk::Request` support for `CLRDATA_REQUEST_REVISION` and `CLRDATA_STACK_WALK_REQUEST_SET_FIRST_FRAME`

[max-charlamb]

#111759 only implements IXCLRDataStackWalk::Request for DACSTACKPRIV_REQUEST_FRAME_DATA. The following options need to be implemented:

• CLRDATA_REQUEST_REVISION
• CLRDATA_STACK_WALK_REQUEST_SET_FIRST_FRAME

CLRDATA_REQUEST_REVISION was handled in #128679 but CLRDATA_STACK_WALK_REQUEST_SET_FIRST_FRAME still remains and it appears windbg uses it.
