feat: implement memory.atomic.notify,wait32,wait64 (#5255)

* feat: implement memory.atomic.notify,wait32,wait64

Added the parking_spot crate, which provides the needed registry for the
operations.

* fix: change trap message for HeapMisaligned

The threads spec test wants "unaligned atomic"
instead of "misaligned memory access".

* tests: add test for atomic wait on non-shared memory

Signed-off-by: Harald Hoyer <harald@profian.com>

* tests: add tests/spec_testsuite/proposals/threads

without pooling and reference types.
Also "shared_memory" is added to the "spectest" interface.

* tests: add atomics_notify.wast

checking that notify with 0 waiters returns 0 on shared and non-shared
memory.

* tests: add tests for atomic wait on shared memory

- return 2 - timeout for 0
- return 2 - timeout for 1000ns
- return 1 - invalid value
