Fix #54707 - parse_trait_item_ now handles interpolated blocks as function body decls

Previously parsing trait items only handled opening brace token and semicolon, I added a branch to the match statement that will also handle interpolated blocks.

Rollup merge of #54833 - abonander:issue-54441, r=petrochenkov 
make `Parser::parse_foreign_item()` return a foreign item or error

Fixes `Parser::parse_foreign_item()` to follow the convention of `parse_trait_item()` and `parse_impl_item()` in that it *must* parse an item or return an error, and then the caller is responsible for detecting the closing delimiter.

This prevents it from looping endlessly on an unexpected token in `ext/expand.rs` where it was also leaking memory by continually pushing to `Parser::expected_tokens` via `Parser::check_keyword()`.

closes #54441

Track whether module declarations are inline (fixes #12590)

To track whether module declarations are inline I added a field `inline: bool` to `ast::Mod`. The main use case is for pretty to know whether it should render the items associated with the module, but perhaps there are use cases for this information to not be forgotten in the AST.

Rollup merge of #54415 - petrochenkov:norollback, r=estebank 
parser: Tweak function parameter parsing to avoid rollback on succesfull path

Since rollback is not perfect and may e.g. leave non-fatal errors after it, we need to make sure compilation fails if it happens.
So in particular case of `fn parse_arg_general` we need to parse the "good" `TYPE` first and only then rollback and recover erroneous `PAT: TYPE` if necessary.
Found when working on https://github.com/rust-lang/rfcs/pull/2544#issuecomment-423293222.
