Removing Zvkb from the "Included in".
vbrev.v is a general purpose instruction and is not needed for our crypto instructions.

* fixing typo Zvkc -> Zvknc in vclmul*

* fixing extension list for vrev8

Cleaned up and updated "Included in at bottom of pages"
Added a new extension Zvkb for Vector Cryptography Bit-Manipulation
   This is a proper subset of Zvbb and only includes the instructions needed for cryptography
Updated Zvkt to say that DIEL doesn't apply to constants included in the instruction encoding such as immediate values  and the zero register.

As discovered by @shakakao and reported by @nibrunieAtSi5
(see https://github.com/riscv/riscv-crypto/issues/331), the
Zvbc-based GHASH logic incorrectly relies on vxor to leave
masked-off lanes undisturbed even though it sets the vector
state with a mask agnostic policy.

The fix is to use ", mu" to request masked-off elements to be
undisturbed.

I did check all proof-of-concept tests in an environment where
masked-off elements get overwritten when "ma" is in effect.
Prior to those fixes only the 'aes-gcm-test' fails, and all
pass with those fixes.

`Zvkb` replaced with `Zvbb` and `Zvbc`

The document is now frozen and ready for public review.

Clarify that vwsll zero-extends the vs2 operand

This follows from the SAIL code and arguably from the instruction's
mnemonic, but make it explicit for readers' benefit.

Fix typo in riscv-crypto-vector-element-groups.adoc

Bumped date and rev

At the request of the Unprivileged Architecture Standing Committee,  we added NIST/ShangMi combined with carryless multiply as a lower cost and lower performance alternative to GCM/GMAC combinations.

fixing vctz vd description

Update vaese128.adoc

Honestly the smallest typo but I figure why not propose the change. vd is used in place of vs2 when describing the purpose of the register (storing plain text).

Zvk code samples  / Proof of Concept (v2)

Bumping the rev and date.

At the recommendation of the ARC, we have removed carryless multiply from the list of extensions included in Zvkn and Zvks.
We recommendation that Zvbc is implemented in RISC-V Vector designs as it enables implementation of CRC and elliptic curve cryptography.

The sm4-test.c file contains a set of functions verifying and
showcasing usage of instructions implementing SM4 algorithm (see [1])
defined by the Zvksed extension (see [2]).

Pre-requisites:

- riscv64-linux-gnu toolchain available in PATH.
- Zvksed-enabled binutils-gdb available in PATH overriding the above
  toolchain.
- Zvksed-enabled Spike available in PATH.
- RISC-V Proxy kernel (riscv-pk) compiled and available in
  ~/RISC-V/riscv64-linux-gnu/bin/pk (can be overridden with PK make
  variable).

The default make target will compile all examples and run them in Spike
simulator.

Example make invocation:
    # Build and run Zvksed tests with default parameters
    make run-sm4
    # Override riscv-pk location
    make run-sm4 PK=/opt/prefix/riscv64-linux-gnu/bin/pk
    # Override target triplet and riscv-pk location
    make run-sm4 TARGET=riscv64-unknown-linux-gnu \
                 PK=/opt/prefix/riscv64-linux-gnu/bin/pk

Make targets:
- sm4-test - compiles the PoC code.
- run-sm4 - Executes the compiled binary in Spike.
- clean - Cleans the build artifacts.

Make variables:
- TARGET - Target triplet to use. By default riscv64-linux-gnu.
- PK - Location of the riscv-pk binary. By default it's
  ~/RISC-V/$(TARGET)/bin/pk

See Makefile for more details.
