  lib/crypto: sha2: Add at_least decoration to fixed-size array params (2025-11-23 12:19:47 -0800)

----------------------------------------------------------------

C supports lower bounds on the sizes of array parameters, using the
static keyword as follows: 'void f(int a[static 32]);'. This allows
the compiler to warn about a too-small array being passed.

As discussed, this reuse of the 'static' keyword, while standard, is a
bit obscure. Therefore, add an alias 'at_least' to compiler_types.h.

Then, add this 'at_least' annotation to the array parameters of
various crypto library functions.
