A scheme for more macro-matcher friendly pre-expansion gating
Pre-expansion gating will now avoid gating macro matchers that did not result in `Success(...)`. That is, the following is now OK despite `box 42` being a valid `expr` and that form being pre-expansion gated:
```rust
macro_rules! m {
($e:expr) => { 0 }; // This fails on the input below due to `, foo`.
(box $e:expr, foo) => { 1 }; // Successful matcher, we should get `2`.
}
fn main() {
assert_eq!(1, m!(box 42, foo));
}
```
Closes https://github.com/rust-lang/rust/issues/65846.

syntax: ABI-oblivious grammar
This PR has the following effects:
1. `extern $lit` is now legal where `$lit:literal` and `$lit` is substituted for a string literal.
2. `extern "abi_that_does_not_exist"` is now *syntactically* legal whereas before, the set of ABI strings was hard-coded into the grammar of the language. With this PR, the set of ABIs are instead validated and translated during lowering. That seems more appropriate.
3. `ast::FloatTy` is now distinct from `rustc_target::abi::FloatTy`. The former is used substantially more and the translation between them is only necessary in a single place.
4. As a result of 2-3, libsyntax no longer depends on librustc_target, which should improve pipe-lining somewhat.
cc @rust-lang/lang -- the points 1-2 slightly change the definition of the language but in a way which seems consistent with our general principles (in particular wrt. the discussions of turning things into semantic errors). I expect this to be uncontroversial but it's worth letting y'all know. :)

We also sever syntax's dependency on rustc_target as a result.
This should slightly improve pipe-lining.
Moreover, some cleanup is done in related code.

gate rustc_on_unimplemented under rustc_attrs
Move `rustc_on_implemented` from the `on_implemented` gate to `rustc_attrs` as it is internal.
Closes #29628

`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a
big performance win (over 10% in some cases) because `DocComment` lets doc
comments (which are common) be represented very cheaply.
`Attribute` gets some new helper methods to ease the transition:
- `has_name()`: check if the attribute name matches a single `Symbol`; for
`DocComment` variants it succeeds if the symbol is `sym::doc`.
- `is_doc_comment()`: check if it has a `DocComment` kind.
- `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant;
panic otherwise.
Fixes #60935.

syntax: Avoid span arithmetic for delimiter tokens
The +/-1 logic is from the time where the whole group had a single span and the delimiter spans had to be calculated from it.
Now the delimiters have their own spans which are constructed by lexer or proc macro API and can be used directly.
If those spans are not perfect, then it should be fixed by tweaking the corresponding lexer logic rather than by trying to add or substract `1` from the span boundaries.
Fixes https://github.com/rust-lang/rust/issues/62524

Remove `PartialEq` and `Eq` from the `SpecialDerives`.
Now that PR #65519 landed, this is the follow-on work of removing `PartialEq` and `Eq` from the set of `SpecialDerives` .

Reduce amount of errors given unclosed delimiter
When in a file with a non-terminated item, catch the error and consume
the block instead of trying to recover it on a more granular way in order to
reduce the amount of unrelated errors that would be fixed after adding
the missing closing brace. Also point out the possible location of the
missing closing brace.
Fix #63690.

Partially revert the early feature-gatings added in #65742.
The intent here is to address #65860 ASAP (in time for beta, ideally), while leaving as much of #65742 around as possible, to make it easier to re-enable later.
Therefore, I've only kept the parts of the revert that re-add the old (i.e. non-early) feature-gating checks that were removed in #65742, and the test reverts.
I've disabled the new early feature-gating checks from #65742 entirely for now, but it would be easy to put them behind a `-Z` flag, or turn them into warnings, which would allow us to keep tests for both the early and late versions of the checks - assuming that's desirable.

Because it's highly magical, which goes against the goal of keeping
`SymbolStr` simple. Plus it's only used in a handful of places that
only require minor changes.

Including removing a bunch of unnecessary `.as_str()` calls, and a bunch
of unnecessary sigils.
