A couple more small cleanups to the BLAKE2s code before these things get
propagated into the BLAKE2b code:
- Drop 'const' from some non-pointer function parameters. It was a bit
excessive and not conventional.
- Rename 'block' argument of blake2s_compress*() to 'data'. This is for
consistency with the SHA-* code, and also to avoid the implication
that it points to a singular "block".
No functional changes.

For consistency with the SHA-1, SHA-2, SHA-3 (in development), and MD5
library APIs, rename blake2s_state to blake2s_ctx.
As a refresher, the ctx name:
- Is a bit shorter.
- Avoids confusion with the compression function state, which is also
often called the state (but is just part of the full context).
- Is consistent with OpenSSL.
Not a big deal, of course. But consistency is nice. With a BLAKE2b
library API about to be added, this is a convenient time to update this.

As was done with the other algorithms, reorganize the BLAKE2s code so
that the generic implementation and the arch-specific "glue" code is
consolidated into a single translation unit, so that the compiler will
inline the functions and automatically decide whether to include the
generic code in the resulting binary or not.
Similarly, also consolidate the build rules into
lib/crypto/{Makefile,Kconfig}. This removes the last uses of
lib/crypto/{arm,x86}/{Makefile,Kconfig}, so remove those too.
Don't keep the !KMSAN dependency. It was needed only for other
algorithms such as ChaCha that initialize memory from assembly code.

Move the contents of arch/arm/lib/crypto/ into lib/crypto/arm/.
The new code organization makes a lot more sense for how this code
actually works and is developed. In particular, it makes it possible to
build each algorithm as a single module, with better inlining and dead
code elimination. For a more detailed explanation, see the patchset
which did this for the CRC library code:
https://lore.kernel.org/r/20250607200454.73587-1-ebiggers@kernel.org/.
Also see the patchset which did this for SHA-512:
https://lore.kernel.org/linux-crypto/20250616014019.415791-1-ebiggers@kernel.org/
This is just a preparatory commit, which does the move to get the files
into their new location but keeps them building the same way as before.
Later commits will make the actual improvements to the way the
arch-optimized code is integrated for each algorithm.
Add a gitignore entry for the removed directory arch/arm/lib/crypto/ so
that people don't accidentally commit leftover generated files.
