URL: https://github.com/apache/arrow-rs/pull/8649

   # Which issue does this PR close?
   
   - Part of #8648.
   
   # Rationale for this change
   
   The format for `DataType::List` includes:
   
   - `List(Int64)`: `nullable = false`, no field name.
   - `List(nullable Int64)`: `nullable = true`, no field name.
   - `List(nullable Int64, field: 'foo')`: `nullable = true` with field `foo`.
   
   `parse_list` now considers those token and parse them correctly.
   
   # What changes are included in this PR?
   
   - Add `Token::Field`.
   - Support parse single quote (because field name is single quoted).
   - Add round trip testcase.
   
   # Are these changes tested?
   
   Yes.
   
   # Are there any user-facing changes?
   
   Yes. This is related to #8351
