Rehome 26 `tests/ui/issues/` tests to other subdirectories under `tests/ui/` [#5 of Batch #2]
Part of rust-lang/rust#133895
Methodology:
1. Refer to the previously written `tests/ui/SUMMARY.md`
2. Find an appropriate category for the test, using the original issue thread and the test contents.
3. Add the issue URL at the bottom (not at the top, as that would mess up stderr line numbers)
4. Rename the tests to make their purpose clearer
Inspired by the methodology that Kivooeo was using.

Some `tests/ui/` housekeeping, to trim down number of tests directly under `tests/ui/`. Part of rust-lang/rust#133895.

- `tests/ui/augmented-assignment-feature-gate-cross.rs`:
- This was *originally* to feature-gate overloaded OpAssign
cross-crate, but now let's keep it as a smoke test.
- Renamed as `augmented-assignment-cross-crate.rs`.
- Relocated under `tests/ui/binop/`.
- `tests/ui/augmented-assignments.rs`:
- Documented test intent.
- Moved under `tests/ui/borrowck/`.
- `tests/ui/augmented-assignment-rpass.rs`:
- Renamed to drop the `-rpass` suffix, since this was leftover from
when `run-pass` test suite was a thing.
- Moved under `tests/ui/binop/`.

While working on #122661, some of these started triggering our "unnecessary parens" lints due to a change in the `assert!` desugaring. A cursory search identified a few more. Some of these have been carried from before 1.0, were a bulk rename from the previous name of `assert!` left them in that state. I went and removed as many of these unnecessary parens as possible in order to have fewer annoyances in the future if we make the lint smarter.
Remove the "which is required by `{root_obligation}`" post-script in
"the trait `X` is not implemented for `Y`" explanation in E0277. This
information is already conveyed in the notes explaining requirements,
making it redundant while making the text (particularly in labels)
harder to read.

Don't delay a bug if we suggest adding a semicolon to the RHS of an assign operator
It only makes sense to delay a bug based on the assumption that "[we] defer to the later error produced by `check_lhs_assignable`" *if* the expression we're erroring actually is an LHS; otherwise, we should still report the error since it's both useful and required.
Fixes#123722
Unify the output of `suggest_assign_value` and `ty_kind_suggestion`.
Ideally we'd make these a single function, but doing so would likely require modify the crate dependency tree.
This improves parallel rustc parallelism by avoiding the bottleneck after each individual `par_body_owners` (because it needs to wait for queries to finish, so if there is one long running one, a lot of cores will be idle while waiting for the single query).
