build: avoid unnecessary dependencies on generated headers This prevents the generation of these headers from also depending on the dependencies of the libs/binaries which consume them. Specifically, this prevents generated test headers (such as test/data/base58_encode_decode.json.h) from depending on the dependencies of test_bitcoin (libcrc32c.a libcrc32c_sse42.a libleveldb.a) Note that this is currently only relevant for Ninja. For more detail, see: https://cmake.org/cmake/help/latest/command/add_custom_command.html

test: Use span for raw data This change allows to drop brittle sizeof calls in favor of the std::span::size method. Other improvements include: * Use of a namespace to mark test and bench data * Use of the modern std::byte * Drop of a no longer used std::vector copy and the bench/data module
