This removes the #[no_sanitize] attribute, which was behind an unstable
feature named no_sanitize. Instead, we introduce the sanitize attribute
which is more powerful and allows to be extended in the future (instead
of just focusing on turning sanitizers off).
This also makes sanitize(kernel_address = ..) attribute work with
-Zsanitize=address
To do it the same as how clang disables address sanitizer, we now
disable ASAN on sanitize(kernel_address = "off") and KASAN on
sanitize(address = "off").
The same was added to clang in https://reviews.llvm.org/D44981.

`NamedValueStr`
Modify `AttributeTemplate` to support list of alternatives for list and name value attribute styles.
Suggestions now provide more correct suggested code:
```
error[E0805]: malformed `used` attribute input
--> $DIR/used_with_multi_args.rs:3:1
|
LL | #[used(compiler, linker)]
| ^^^^^^------------------^
| |
| expected a single argument here
|
help: try changing it to one of the following valid forms of the attribute
|
LL - #[used(compiler, linker)]
LL + #[used(compiler)]
|
LL - #[used(compiler, linker)]
LL + #[used(linker)]
|
LL - #[used(compiler, linker)]
LL + #[used]
|
```
instead of the prior "masking" of the lack of this feature by suggesting pipe-separated lists:
```
error[E0805]: malformed `used` attribute input
--> $DIR/used_with_multi_args.rs:3:1
|
LL | #[used(compiler, linker)]
| ^^^^^^------------------^

|
help: try changing it to one of the following valid forms of the attribute
|
LL - #[used(compiler, linker)]
LL + #[used(compiler|linker)]
|
LL - #[used(compiler, linker)]
LL + #[used]
|
```

for unsized types
|
|
Gets rid of two top-level UI tests which is always great.
Furthermore, move `need-crate-arg-ignore-tidy$x.rs`
from `command/` to `invalid-compile-flags/`.
`command/` concerns `std::process::Command` tests, not CLI tests.

```
error[E0610]: `{integer}` is a primitive type and therefore doesn't have fields
--> $DIR/attempted-access-non-fatal.rs:7:15
|
LL | let _ = 2.l;
| ^
|
help: if intended to be a floating point literal, consider adding a `0` after the period and a `f64` suffix
|
LL - let _ = 2.l;
LL + let _ = 2.0f64;
|
```

They've been deprecated for four years.
This commit includes the following changes.
- It eliminates the `rustc_plugin_impl` crate.
- It changes the language used for lints in
`compiler/rustc_driver_impl/src/lib.rs` and
`compiler/rustc_lint/src/context.rs`. External lints are now called
"loaded" lints, rather than "plugins" to avoid confusion with the old
plugins. This only has a tiny effect on the output of `-W help`.
- E0457 and E0498 are no longer used.
- E0463 is narrowed, now only relating to unfound crates, not plugins.
- The `plugin` feature was moved from "active" to "removed".
- It removes the entire plugins chapter from the unstable book.
- It removes quite a few tests, mostly all of those in
`tests/ui-fulldeps/plugin/`.
Closes #29597.

Nowadays there is an `invalid-compile-flags` folder, thus move this
one there.
