Rollup merge of #65776 - nnethercote:rename-LocalInternedString-and-more, r=estebank 
Rename `LocalInternedString` and more

This PR renames `LocalInternedString` as `SymbolStr`, removes an unnecessary `impl` from it, improves comments, and cleans up some `SymbolStr` uses.

Rollup merge of #66054 - petrochenkov:delspan, r=estebank 
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

f49f388713 Auto merge of #65838 - estebank:resilient-recovery, r=Centril 
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.

d0db290039 Remove the AsRef impl for SymbolStr. 
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.

Rollup merge of #65455 - nnethercote:avoid-unnecessary-TokenTree-to-TokenStream-conversions, r=petrochenkov 
Avoid unnecessary `TokenTree` to `TokenStream` conversions

A `TokenStream` contains any number of `TokenTrees`. Therefore, a single `TokenTree` can be promoted to a `TokenStream`. But doing so costs two allocations: one for the single-element `Vec`, and one for the `Lrc`. (An `IsJoint` value also must be added; the default is `NonJoint`.)

The current code converts `TokenTree`s to `TokenStream`s unnecessarily in a few places. This PR removes some of these unnecessary conversions, both simplifying the code and speeding it up.
