[rustdoc-json] Make `header` a vec of modifiers, and FunctionPointer consistent

Bumps version number and adds tests, this is a breaking change. I can split this into two (`is_unsafe` -> `header` and `header: Vec<Modifiers>`) if desired.

Rationale: Modifiers are individual notes on a function, it makes more sense for them to be a list of an independent enum over a String which is inconsistently exposing the HIR representation (prefix_str vs custom literals).
Function pointers currently only support `unsafe`, but there has been talk on and off about allowing them to also support `const`, and this makes handling their modifiers consistent with handling those of a function, allowing better shared code.

Hi.

Updated Cargo.toml's for smallvec due to RUSTSEC-2021-0003 and Cargo.toml in separate commit.

Affected function `SmallVec::insert_many` looks like don't was used directly in rust, but can be somewhere in deps.

There should be some mechanism to not to do this kind of things manually, like dependabot. Actually, dependabot supports rust and can check security articles (at least that noted in description).

Visit more targets when validating attributes

This begins to address #80048, allowing for additional validation of attributes.

There are more refactorings that can be done, though I think they should be tackled in additional PRs:
* ICE when a builtin attribute is encountered that is not checked
* Move some of the attr checking done `ast_validation` into `rustc_passes`
  * note that this requires a bit of additional refactoring, especially of extern items which currently parse attributes (and thus are a part of the AST) but do not possess attributes in their HIR representation.
* Rename `Target` to `AttributeTarget`
* Refactor attribute validation completely to go through `Visitor::visit_attribute`.
  * This would require at a minimum passing `Target` into this method which might be too big of a refactoring to be worth it.
  * It's also likely not possible to do all the validation this way as some validation requires knowing what other attributes a target has.

Require passing an `AttrWrapper` to `collect_tokens_trailing_token`

It represents the most invasive part of that PR, requiring changes in
every caller of `parse_outer_attributes`

In order to eagerly expand `#[cfg]` attributes while preserving the
original `TokenStream`, we need to know the range of tokens that
corresponds to every attribute target. This is accomplished by making
`parse_outer_attributes` return an opaque `AttrWrapper` struct. An
`AttrWrapper` must be converted to a plain `AttrVec` by passing it to
`collect_tokens_trailing_token`. This makes it difficult to accidentally
construct an AST node with attributes without calling `collect_tokens_trailing_token`,
since AST nodes store an `AttrVec`, not an `AttrWrapper`.

As a result, we now call `collect_tokens_trailing_token` for attribute
targets which only support inert attributes, such as generic arguments
and struct fields. Currently, the constructed `LazyTokenStream` is
simply discarded. Future PRs will record the token range corresponding
to the attribute target, allowing those tokens to be removed from an
enclosing `collect_tokens_trailing_token` call if necessary.
