Merge #13309: Directly operate with CMutableTransaction in SignSignature
6b8b63af1461dc11ffd813401e2c36fa44656715 Generic TransactionSignatureCreator works with both CTransaction and CMutableTransaction (Martin Ankerl)
Pull request description:
Refactored `TransactionSignatureCreator` into a templated `GenericTransactionSignatureCreator` that works with both `CMutableTransaction` and `CTransaction`.
The advantage is that now in `SignSignature`, the `MutableTransactionSignatureCreator` can now operate directly with the `CMutableTransaction` without the need to copy the data into a `CTransaction`.
Running all unit tests brings a very noticable speedup on my machine:

running only `--run_test=transaction_tests/test_big_witness_transaction`:
16.7 sec before this change
5.9 sec with this change
--------

This relates to my first attempt with the const_cast hack #13202, and to the slow unit test issue #10026.
Also see #13050 which modifies the tests but not the production code (like this PR) to get a speedup.
