This commit removes Wasmtime's dependency on the `region` crate. The motivation for this came about when I was updating dependencies and saw that `region` had a new major version at 3.0.0 as opposed to our currently used 2.3 track. In reviewing the use cases of `region` within Wasmtime I found two trends in particular which motivated this commit: * Some unix-specific areas of `wasmtime_runtime` use `rustix::mm::mprotect` instead of `region::protect` already. This means that the usage of `region::protect` for changing virtual memory protections was already inconsistent. * Many uses of `region::protect` were already in unix-specific regions which could make use of `rustix`. Overall I opted to remove the dependency on the `region` crate to avoid chasing its versions over time. Unix-specific changes of protections were easily changed to `rustix::mm::mprotect`. There were two locations where a windows/unix split is now required and I subjectively ruled "that seems ok". Finally removing `region` also meant that the "what is the current page size" query needed to be inlined into `wasmtime_runtime`, which I have also subjectively ruled "that seems fine". Finally one final refactoring here was that the `unix.rs` and `linux.rs` split for the pooling allocator was merged. These two files already only differed in one function so I slapped a `cfg_if!` in there to help reduce the duplication.
