Consensus: DIP-0020: Dash opcode updates - OP_CAT and OP_SPLIT. (#3824)
* DIP-0020: Dash opcode updates - enable OP_CAT and OP_SPLIT (renamed from OP_SUBSTR)

* DIP-0020: Dash opcode updates - DEPLOYMENT_V17 activates dip0020 opcodes

* Add/tweak MAX_SCRIPT_ELEMENT_SIZE tests for OP_CAT and OP_SPLIT

* Check nDefaultMaxNumSize in OP_SPLIT tests

* Purify DISABLED_OPCODE tests for OP_CAT and OP_SPLIT, fix DoTest to actually preserve the DIP0020 flag

* Fix `warning: '&' within '|' [-Wbitwise-op-parentheses]`

* Rework/simplify feature_dip0020_activation.py

* DIP-0020: Remove functionally redundant tests.

* Fix file permissions for feature_dip0020_activation.py

* DIP-0020: fix typo

* Update src/test/script_tests.cpp
