rfc3052 followup: Remove authors field from Cargo manifests

Since RFC 3052 soft deprecated the authors field, hiding it from
crates.io, docs.rs, and making Cargo not add it by default, and it is
not generally up to date/useful information for contributors, we may as well
remove it from crates in this repo.

3cf820e17d rfc3052: Remove authors field from Cargo manifests
Since RFC 3052 soft deprecated the authors field anyway, hiding it from
crates.io, docs.rs, and making Cargo not add it by default, and it is
not generally up to date/useful information, we should remove it from
crates in this repo.

Checking that function is const if marked with rustc_const_unstable

Fixes #69630

This one is still missing tests to check the behavior but I checked by hand and it seemed to work.
I would not mind some direction for writing those unit tests!

remove stdcall test, failing CI test

C abi is already tested in this, so it is not that useful to test another one.
The tested code is blind to which specific ABI for now, as long as it's not an intrinsic one

E0716: clarify that equivalent code example is erroneous

In E0716, there is a code block that is equivalent to the erroneous
code example. Especially when viewed with `rustc --explain`, it's
not obvious that it is also erroneous, and some users have been
confused when they try to change their code to match the erroneous
equivalent.

Rollup merge of #86148 - FabianWolff:issue-85855, r=varkor
Check the number of generic lifetime and const parameters of intrinsics

This pull request fixes #85855. The current code for type checking intrinsics only checks the number of generic _type_ parameters, but does not check for an incorrect number of lifetime or const parameters, which can cause problems later on, such as the ICE in #85855, where the code thought that it was looking at a type parameter but found a lifetime parameter:
```
error: internal compiler error: compiler/rustc_middle/src/ty/generics.rs:188:18:
    expected type parameter, but found another generic parameter
```

The changes in this PR add checks for the number of lifetime and const parameters, expand the scope of `E0094` to also apply to these cases, and improve the error message by properly pluralizing the number of expected generic parameters.

swap function order for better read flow
When having the order

```
foo.bar(); // we can now use this method since i32 implements the Foo trait

[...]

impl Foo for i32

the `// we can now use this method` comment is less clear to me.

further split up const_fn feature flag

This continues the work on splitting up `const_fn` into separate feature flags:
* `const_fn_trait_bound` for `const fn` with trait bounds
* `const_fn_unsize` for unsizing coercions in `const fn` (looks like only `dyn` unsizing is still guarded here)

I don't know if there are even any things left that `const_fn` guards... at least libcore and liballoc do not need it any more.

`@oli-obk` are you currently able to do reviews?
