Since https://github.com/rust-lang/rust/pull/95503, `library/std` means
"build just std and its dependencies"; to get the old behavior that built
`proc_macro` and `test`, you need `x build library`.
- Update `library/std` to `library`
- Remove the `-i` suggestions; `incremental = true` is already the default for most profiles, in
which case `-i` does nothing. If you don't have incremental enabled, I still think suggesting `-i`
is bad idea, because it's easy to forget once, at which point you'll end up rebuilding the whole
compiler / standard library.
- Remove a few repetitive sections and don't discuss incremental in such detail
Incremental works well enough that it should "just work" for most people;
I don't think it needs multiple paragraphs of explanation so early in the guide.
- Clarify that `test library/std` *only* tests libstd in a few places
Document how to use WPA to profile rustc and what the normal workflow
should be for investigating bootstrap memory usage issues.

Specifically, `> $1` causes it to write into the file $1 if it exist
And `> ./x.py` is particularly bad because it overwrite the script with
empty spaces...
