Merge bitcoin/bitcoin#22257: test: refactor: various (de)serialization helpers cleanups/improvements
bdb8b9a347e68f80a2e8d44ce5590a2e8214b6bb test: doc: improve doc for `from_hex` helper (mention `to_hex` alternative) (Sebastian Falbesoner)
191405420815d49ab50184513717a303fc2744d6 scripted-diff: test: rename `FromHex` to `from_hex` (Sebastian Falbesoner)
a79396fe5f8f81c78cf84117a87074c6ff6c9d95 test: remove `ToHex` helper, use .serialize().hex() instead (Sebastian Falbesoner)
2ce7b47958c4a10ba20dc86c011d71cda4b070a5 test: introduce `tx_from_hex` helper for tx deserialization (Sebastian Falbesoner)
Pull request description:
There are still many functional tests that perform conversions from a hex-string to a message object (deserialization) manually. This PR identifies all those instances and replaces them with a newly introduced helper `tx_from_hex`.
Instances were found via
* `git grep "deserialize.*BytesIO"`
and some of them manually, when it were not one-liners.
Further, the helper `ToHex` was removed and simply replaced by `.serialize().hex()`, since now both variants are in use (sometimes even within the same test) and using the helper doesn't really have an advantage in readability. (see discussion https://github.com/bitcoin/bitcoin/pull/22257#discussion_r652404782)
