Add measureme integration for profiling the interpreted program 
This PR uses the `measureme` crate to profile the call stack of the
program being interpreted by Miri. This is accomplished by starting a
measureme 'event' when we enter a function call, and ending the event
when we exit the call. The `measureme` tooling can be used to produce a
call stack from the generated profile data.

Limitations:
* We currently record every single entry/exit. This might generate very
  large profile outputs for programs with a large number of function
  calls. In follow-up work, we might want to explore sampling (e.g. only
  recording every N function calls).
* This does not integrate very well with Miri's concurrency support.
  Each event we record starts when we push a frame, and ends when we pop
  a frame. As a result, switching between virtual threads will cause
  events from different threads to be interleaved. Additionally, the
  recorded for a particular frame will include all of the work Miri does
  before that frame completes, including executing another thread.

The `measureme` integration is off by default, and must be enabled via
`-Zmiri-measureme=<output_name>`

Skip doctests of `proc-macro` crates

Fixes #1813.

Verified that the newly added tests failed without the `cargo-miri` change and pass with normal `cargo test`.

get rid of some `Rc`

Now that the memory access hooks get references to `MemoryExtra`, we can avoid refcounting for the global state of Stacked Borrows and the data race detector.
