Merge bitcoin/bitcoin#30618: test: support std::optional in BOOST_CHECK_* and increase FromUserHex fuzz feature coverage

Browse Source 
1eac96a503 Compare FromUserHex result against other hex validators and parsers (Lőrinc)
19947863e1 Use BOOST_CHECK_EQUAL for optional, arith_uint256, uint256, uint160 (Lőrinc)
743ac30e34 Add std::optional support to Boost's equality check (Lőrinc)

Pull request description:

  Enhanced `FromUserHex` coverage by:

  * Added `std::optional` support to `BOOST_CHECK_EQUAL`, allowing direct comparisons of `std::optional<T>` with other `T` expected values.
  * Increased fuzz testing for hex parsing to validate against other hex validators and parsers.

  ----

  * Use BOOST_CHECK_EQUAL for https://github.com/bitcoin/bitcoin/pull/30569#discussion_r1706637780 arith_uint256, uint256, uint160

  Example error before:
  > unknown location:0: fatal error: in "validation_chainstatemanager_tests/chainstatemanager_args": std::bad_optional_access: bad_optional_access
  test/validation_chainstatemanager_tests.cpp:781: last checkpoint

  after:
  > test/validation_chainstatemanager_tests.cpp:801: error: in "validation_chainstatemanager_tests/chainstatemanager_args": check set_opts({"-assumevalid=0"}).assumed_valid_block == uint256::ZERO has failed [std::nullopt != 0000000000000000000000000000000000000000000000000000000000000000]
