Edit punctuation in doc comment for rustc_middle::lint::LintSource::CommandLine.

Expand abbreviations for "incremental compliation".

Also added the word "to" to the description of CacheEncoder.

Each label needs to be separated by a comma (see the ICE issue template
for an example of correct usage).

Fix typo in rustc_middle::ty::inhabitedness::DefIdForest docs.

It doesn't add anything since every topic in
`t-compiler/wg-prioritization/alerts` is about prioritization.
And it makes it harder to see the issue title, which is what the topic
is actually about.

Edition evaluation is kept lazy because it may be expensive.

Add descriptions of `AccessLevel` and `AccessLevels`.

Add missing punctuation.

`replace_prefix` is currently implemented as a method but has no real relation
to the struct it is implemented on. Turn it into a closure and move it into the
only method from which it is called.

This corrects the return type in docs for yield_in_source method.

Closes rust-lang#80287.
