Use the psm crate to figure out the current stack pointer (#2358)

Currently the runtime needs to acquire the current stack pointer so it
can set a limit for where if the wasm stack goes below that point it
will abort the wasm code. Acquiring the stack pointer is done in a
brittle way right now which involves looking at the address of what we
hope is an on-stack structure. This turns out to not work at all with
ASan as well.

Instead this commit switches to the `psm` crate which is used by the
Rust compiler team for stack manipulation, namely a coarse version of
segmented stacks to avoid stack overflow in the compiler. We don't need
most of the implementation of `psm`, just the `stack_pointer` function,
but it shouldn't be a burden to bring in!

Closes #2344
