7a276c8a - [lldb] Fix logic error in AppleObjCTypeEncodingParser (#137067)

[lldb] Fix logic error in AppleObjCTypeEncodingParser (#137067) Fixes parsing of an ObjC type encoding such as `{?="a""b"}`. Parsing of such a type encoding would lead to an assert. This was observed when running `language objc class-table dump`. The function `ReadQuotedString` consumes the closing quote, however one of its two callers (`ReadStructElement`) was also consuming a quote. For the above type encoding, where two quoted strings occur back to back, the parser would unintentionally consume the opening quote of the second quoted string - leaving the remaining text with an unbalanced quote. This changes fixes `ReadStructElement` to not consume a quote after calling `ReadQuotedString`. For callers to know whether a string was successfully parsed, `ReadQuotedString` now returns an optional string.
