Adopt let else in more places

Continuation of rust-lang#89933, rust-lang#91018, rust-lang#91481, rust-lang#93046, rust-lang#93590, rust-lang#94011.

I have extended my clippy lint to also recognize tuple passing and match statements. The diff caused by fixing it is way above 1 thousand lines. Thus, I split it up into multiple pull requests to make reviewing easier. This is the biggest of these PRs and handles the changes outside of rustdoc, rustc_typeck, rustc_const_eval, rustc_trait_selection, which were handled in PRs rust-lang#94139, rust-lang#94142, rust-lang#94143, rust-lang#94144.

This avoids a situation where a file is at the border of the limit,
and alternates between hitting the limit and not hitting it, causing
a back and forth of addition of the ignore-tidy-linelength directive.

As an example, consider the ignore-tidy-filelength of compiler/rustc_typeck/src/collect.rs.

It was added in 2ca4964, removed in
37354eb, added again in 448d076,
removed in 3171bd5, added in 438826f,
and rust-lang#94142 is going to remove it again.

To avoid this back and forth, we exempt files from the unneccessary
ignoring warning that have length of at least 70% of the limit.
