Merge #13396: Drop unused arith_uint256 ! operator

2acd1d6716959b99e751cf85a7c47aaa383e937f Drop uint 256 not operator (Ben Woosley)

Pull request description:

  All the other operators are integer or bitwise operations, and this is unused
  apart from tests.

  Note attempting to call `!` on `arith_uint256` results in a build error after this change:
  ```
  test/arith_uint256_tests.cpp:201:17: error: invalid argument type 'const arith_uint256' to unary expression
      BOOST_CHECK(!ZeroL);
  ```
