Merge wasmtime-jit and wasmtime-profiling (#3247)

* Merge `wasmtime-jit` and `wasmtime-profiling`

This commit merges the `wasmtime-profiling` crate into the
`wasmtime-jit` crate. It wasn't really buying a ton being a separate
crate and an upcoming refactoring I'd like to do is to remove the
`FinishedFunctions` structure. To enable the profilers to work as they
used to this commit changes them to pass `CompiledModule` as the
argument, but this only works if the profiling trait can see the
`CompiledModule` type.

* Fix a length calculation
