Issue #24619: Simplify async/await tokenization.
This commit simplifies async/await tokenization in tokenizer.c, tokenize.py & lib2to3/tokenize.py. Previous solution was to keep a stack of async-def & def blocks, whereas the new approach is just to remember position of the outermost async-def block. This change won't bring any parsing performance improvements, but it makes the code much easier to read and validate.
