This simplifies the Lexical Analysis section on Names (but keeps it technically correct) by putting all the info about non-ASCII characters in a separate (and very technical) section.

It uses a mental model where the parser doesn't handle Unicode complexity “immediately”, but:

- parses any non-ASCII character (outside strings/comments) as part of a name, since these can't (yet) be e.g. operators
- normalizes the name
- validates the name, using the xid_start/xid_continue sets

…) (GH-142227)

Much of the information was duplicated in stdtypes.rst; this PR keeps
lexical/syntactical details in Lexical Analysis and the evaluation & runtime
behaviour in Standard types, with cross-references between the two.
Since the t-string section only listed differences from f-strings, and the
grammar for the two is equivalent, that section was moved to Standard types
almost entirely.

… service in http.server (GH-142216)

The CGI server on Windows could consume the amount of memory specified
in the Content-Length header of the request even if the client does not
send such much data. Now it reads the POST request body by chunks,
therefore the memory consumption is proportional to the amount of sent
data.
