Fix long lines which rustfmt fails to format #136606

rustfmt fails to format this match expression, because it has several long string literals over the maximum line width. This seems to exhibit rustfmt issues #3863 (Gives up on chains if any line is too long) and #3156 (Fail to format match arm when other arm has long line).

Format it with a large line width (e.g., by setting max_width = 200 in rustfmt.toml) and, in case the rustfmt bugs are later fixed, mark it with #[rustfmt::skip], as it is more legible with each case on one line.

Also, the periods and possibly the sentence capitalization seem to go against the style for Rust error messages. But, since they're sourced from the UEFI Specification, I left them be. I'm not sure whether they should be changed.

Fix long lines which rustfmt fails to format

rustfmt fails to format this match expression, because it has several long string literals over the maximum line width. This seems to exhibit rustfmt issues [rust-lang#3863](rust-lang/rustfmt#3863) (Gives up on chains if any line is too long) and [rust-lang#3156](rust-lang/rustfmt#3156) (Fail to format match arm when other arm has long line).

Format it with a large line width (e.g., by setting `max_width = 200` in rustfmt.toml) and, in case the rustfmt bugs are later fixed, mark it with `#[rustfmt::skip]`, as it is more legible with each case on one line.
