baac704391 Fix s_pclmul_is_supported() cache flag on MSVC 
Move initialized=1 out of the #else branch so that on MSVC it doesn't
call __cpuid every time.

cf29490bfc Introduce LTC_ALIGNED_BUF_SIZE(). [skip ci] 
Since there's absolutely no way to ensure that a struct is somehow
aligned -- all those compile-time mechanism are best-effort and no
guarantee -- we align the necessary buffers at run-time.

AES-NI already introduced that, let's improve a bit upon its usage.

c68b9c0b3f Minor changes of argon2 implementation. 
* We continue using `LTC_ARGCHK()` until we've decided on something else.
* Call the enum/struct the same as the typedef.
* Some other small adjustments/fixes.

46e0137e55 Optimize gcm_gf_mult using PCLMULQDQ and PMULL 
GCM table setup disproportionately hurts LTC performance
with small messages. Disabling LTC_GCM_TABLES helps for
small payloads but hurts large ones.

This implements hardware carry-less multiplication for GCM that
performs well for both cases using PCLMULQDQ on x86/x86_64 and
PMULL on AArch64.

There are no public API changes.

These features can be disabled with LTC_NO_GCM_PCLMUL,
LTC_NO_GCM_PMULL, or LTC_NO_ASM. LTC_GCM_TABLES is disabled
automatically when no opt-out macro is set.
