`OsStr` has historically kept its implementation details private out of
concern for locking us into a specific encoding on Windows.
This is an alternative to rust-lang#95290 which proposed specifying the encoding on Windows. Instead, this
only specifies that for cross-platform code, `OsStr`'s encoding is a superset of UTF-8 and defines
rules for safely interacting with it
At minimum, this can greatly simplify the `os_str_bytes` crate and every
arg parser that interacts with `OsStr` directly (which is most of those
that support invalid UTF-8).
This option was introduced three years ago, but it's never been
meaningfully used, and `default` is the only acceptable value.
Also, I think the `Partition` trait presents an interface that is too
closely tied to the existing strategy and would probably be wrong for
other strategies. (My rule of thumb is to not make something generic
until there are at least two instances of it, to avoid this kind of
problem.)
Also, I don't think providing multiple partitioning strategies to the
user is a good idea, because the compiler already has enough obscure
knobs.
This commit removes the option, along with the `Partition` trait, and
the `Partitioner` and `DefaultPartitioning` types. I left the existing
code in `compiler/rustc_monomorphize/src/partitioning/default.rs`,
though I could be persuaded that moving it into
`compiler/rustc_monomorphize/src/partitioning/mod.rs` is better.

offset_of: don't require type to be `Sized`
Fixesrust-lang#112051
~~The RFC [explicitly forbids](https://rust-lang.github.io/rfcs/3308-offset_of.html#limitations) non-`Sized` types, but it looks like only the fields being recursed into were checked. The sized check also seemed to have been completely missing for tuples~~

change `BorrowKind::Unique` to be a mutating `PlaceContext`
fixesrust-lang#112056
I believe that `BorrowKind::Unique` is a footgun in general, so I added a FIXME and opened rust-lang#112072. This is a bit too involved for this PR though.

Group rfcs tests
This moves all RFC tests to `tests/ui/rfcs/rfc-NNNN-title-title-title/...`
I had to rename some tests due to conflicts, but otherwise this is just a move.

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.
How do I rebase?
Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:
git checkout rollup-9kt7eav(switch to your branch)
git fetch upstream master(retrieve the latest master)
git rebase upstream/master -p(rebase on top of it)
Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
git push self rollup-9kt7eav --force-with-lease(update this PR)
Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.
Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.
