870bc295d4 Document the entire AutoRTFM user-facing API and deprecate a bunch of functions that most users should not use (move these to the ForTheRuntime namespace to hopefully make it clear what shouldn't be called by those of us not working on the runtime!).

3a200d0b65 Move the global GAutoRTFMRuntimeEnabled to only be exposed to functions 
Move GAutoRTFMRuntimeEnabled to be an enum with 3 states:
  Disabled
  Enabled
  ForcedDisabled

ForcedDisabled will prevent this from ever being allowed to be turned on

2fe7eda1f0 autortfm: 
- remove explicit operator new/delete instrumentation. these operators can be instrumented directly by the application by overriding them, otherwise calling one from transactional code will abort when trying to find the instrumented version
- add auto rtfm instrumentation to the FMemory allocator
- remove 'will_deallocate' since it does nothing and required the runtime to be able to get the alloced size which isn't easy to do from the runtime
- Transact now executes the work item when it's compiled away, assuming that we will wrap this around existing code that we still want to execute when non-instrumented

7a7d71868f First go at the AutoRTFM Open API for the VM. This is definitely crunchy. 
Adds StartTransaction, RecordOpenWrite, WriteMemory, and some others.
Replaces Abort with AbortTransaction
