Auto merge of #108089 - Zoxc:windows-tls, r=bjorn3
Support TLS access into dylibs on Windows This allows access to `#[thread_local]` in upstream dylibs on Windows by introducing a MIR shim to return the address of the thread local. Accesses that go into an upstream dylib will call the MIR shim to get the address of it. `convert_tls_rvalues` is introduced in `rustc_codegen_ssa` which rewrites MIR TLS accesses to dummy calls which are replaced with calls to the MIR shims when the dummy calls are lowered to backend calls. A new `dll_tls_export` target option enables this behavior with a `false` value which is set for Windows platforms. This fixes https://github.com/rust-lang/rust/issues/84933.
