build: remove confusing and inconsistent disable-asm option
1. It didn't actually disable asm usage in our code. Regardless of the setting,
asm is used in random.cpp and support/cleanse.cpp.
2. The value wasn't forwarded to libsecp as a user might have reasonably
expected.
3. We now have the DISABLE_OPTIMIZED_SHA256 define which is what disable-asm
actually did in practice.
If there is any desire, we can hook DISABLE_OPTIMIZED_SHA256 up to a new
configure option that actually does what it says.
