This commit is a result of the discussion on rust-lang#128475 and incorporates parts of rust-lang#109807 as well. This is all done as a new page of documentation for the `wasm32-unknown-unknown` target which previously did not exist. This new page goes into details about the preexisting target and additionally documents the expectations for WebAssembly features and code generation. The tl;dr is that LLVM will enable features over time after most engines have had support for awhile. Compiling without features requires `-Ctarget-cpu=mvp` to rustc plus `-Zbuild-std` to Cargo. Closes rust-lang#109807 Closes rust-lang#128475

…r=cuviper Add a missing compatibility note in the 1.80.0 release notes rust-lang#99969 missed being included in the release notes. As discussed [on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/241545-t-release/topic/.2399969.20missed.20the.20release.20notes/near/463002451).

Stabilize feature `char_indices_offset`
Stabilized API:
```rust
impl CharIndices<'_> {
pub fn offset(&self) -> usize;
}
```
Tracking issue: rust-lang#83871
Closes rust-lang#83871
I also attempted to improved the documentation to make it more clear that it returns the offset of the character that will be returned by the next call to `next()`.

This PR fixes the handling of spans with different context (aka macro arguments) than the primary expression within the different `{drop,forget}ing_copy_types` and `{drop,forget}ing_references` lints.
