chore(core): remove sha1 from regular FW

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…

chore(crypto): replace `int` by `size_t` for nonnegative parameters
