tests: change Python code style to pass ruff checks

Most of the changes consisted of removing unused imports and unnecessary
f-strings.

tests: fix some Python typing issues

These otherwise raise errors in pytype. A few problematic methods
weren't being used and are deleted.

asyn-ares: remove typecast, fix expire

- Use the appropriate variable type for the curlx_tvtoms() return code:
timediff_t and remove the typecast.

- Simplify the function and avoid the odd expire adjustment that
probably is a rest from ancient days when the expire function did not
handle zero millisecond timeouts.

Since we see Windows fails of 1915, add tracing and a connect timeout.
The test uses a port no one is supposed to listen on, but Windows has
this weird wait logic. So, set a short timeout.

urlapi: normalize the IPv6 address

As the parsing and address "regeneration" are done anyway, we might as
well use the updated version in the result and thereby A) get a
normalized (and lower cased) version of the address and B) avoid a

Updated test 1560 to verify.

openssl quic: populate x509 store before handshake

Since OpenSSL does its own send/recv internally, we may miss the moment
to populate the x509 store right before the server response. Do it
instead before we start the handshake, at the loss of the time to set
this up.

DEPRECATE: remove hyper in January 2025

Previously this document stated we would do it after February, but now
it will be done already for the first January 2025 release.

The reason being that since we decided to deprecate hyper, the
degradation speed has increased as now no one bothers to fix issues in
the hyper side of things. Also: not a single soul has yet spoken up in
favor of keeping the support.
