0e19fb92e1 While parsing enum variant, the error message always disappear 
Because the error message that emit out is from main error of parser
The information of enum variant disappears while parsing enum variant with error
We only check the syntax of expecting token, i.e, in case #103869
It will error it without telling the message that this error is from pasring enum variant.
Propagate the sub-error from parsing enum variant to the main error of parser by chaining it with map_err
Check the sub-error before emitting the main error of parser and attach it.
Fix #103869

Show a note where a macro failed to match 
This shows a small note on what the macro matcher was currently
processing to aid with "no rules expected the token X" errors.

379ae12a1d expand: Remove ParseSess::missing_fragment_specifiers 
It was used for deduplicating some errors for legacy code which are mostly deduplicated even without that, but at cost of global mutable state, which is not a good tradeoff.

Show macro name in 'this error originates in macro' message 
When there are multiple macros in use, it can be difficult to tell
which one was responsible for producing an error.

02eae432e7 Promote missing_fragment_specifier to hard error 
It has been deny_by_default since 2017 (and warned for some time
before that), so it seems reasonable to promote it.

The specific technical motivation to do this now is to remove a field
from `ParseSess` -- it is a global state, and global state makes
extracting libraries annoying.

Closes #40107

bfa5f27847 introduce unescape module 
Currently, we deal with escape sequences twice: once when we lex a
string, and a second time when we unescape literals. This PR aims to
remove this duplication, by introducing a new `unescape` mode as a
single source of truth for character escaping rules
