core: crypto: refactor aes-gcm implementation

Adds struct internal_ghash_key to represent the ghash key instead of
some lose fields inside struct internal_aes_gcm_state.

Software of CE configuration is done explicitly in
core/crypto/aes-gcm-sw.c, dropping the __weak attribute for all
functions but internal_aes_gcm_update_payload_block_aligned() which
is only overridden with CFG_CRYPTO_WITH_CE=y in AArch64.

Content of aes-gcm-private.h is moved into internal_aes-gcm.h.

internal_aes_gcm_gfmul() is made available for generic GF
multiplication.

The CE versions of internal_aes_gcm_expand_enc_key() and
internal_aes_gcm_encrypt_block() are now only wrappers around
crypto_accel_aes_expand_keys() and crypto_accel_aes_ecb_enc().
