Remove workarounds for Rust bugs in Yoke, DataPayload

[sffc]

There are docs tests in the yoke and icu_provider crate that will begin compiling in Rust 1.56 or 1.57, due to fixes to upstream bugs rust-lang/rust#86703 (fixed in 1.56) and rust-lang/rust#88446 (fixed in 1.57). This issue is to track steps to update to these Rust versions once stabilized and at the same time update our docs tests.

As part of this bug, also remove the obsolete with_capture variants of the functions, and fix alignment between Yoke and DataPayload.

This is partially fixed by #1090 and #1135, but we are now blocked by the following bugs:

• for<'a> Fn(<A as B<'a>>::C) fails incosistently and requires unnecessary type annotations rust-lang/rust#90875 (_with_capture)
• HRTB bounds not resolving correctly (take 2) rust-lang/rust#89196 (YokeTraitHack)

This new state is reflected in #1134. Moving to the 0.5 milestone to revisit.

There may be a workaround that means we can get rid of _with_capture: rust-lang/rust#89436 (comment) (but it requires more annotations)
