Don't fail to remove files if they are missing

[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.

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`

This is a pure refactoring split out from #80689.
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.
