Re-organize platform-specific shims

Move platform-specific code to `shims::{posix::{linux, macos}, windows}`. Also make it private in these modules to ensure we are reasonably structured.

This seems to be the latest version that works before *something* broke -- so let's make this a baseline.

Add file sync shims

This PR adds shim implementations for these related file syncing functions.
* `fsync`, for POSIX targets, backed by `File::sync_all()`
* `fdatasync`, for POSIX targets, backed by `File::sync_data()`
* `fcntl` with command `F_FULLFSYNC`, for macOS targets, backed by `File::sync_all()`
* `sync_file_range`, for Linux targets, backed by `File::sync_data()`

Just quickly get things to work with the TLS changes.

Eventually I'll look into properly making use of the new infrastructure, but I don't have time right now.

Remove pointer arithmetic intrinsics

**Do Not Merge** until https://github.com/rust-lang/rust/pull/71500 is in nightly.

As https://github.com/rust-lang/rust/pull/71500 implements `offset` and `arith_offset` in rustc's MIR interpreter, these implementations can now be removed from miri. Also, the `pointer_offset_inbounds` method has been moved to the main MIR engine, so that too can be removed.
