Add support for the Zvk* ISA extensions (#333)

* Add initial vector support

This patch includes initial vector support for ACT.
It defines a couple of new macros that allow to test
vector instructions.

Key features:
- defines four GPRs that have be reserved
- enablement code for vector unit
- helper macro to update test signatures
- support for all SEW configurations (8, 16, 32, 64 bits)
- support for all immediate AVL values (0..31 elements)
- If VLENB indicates that a test can't be executed, then it will be skipped
- Support for several instruction formats (VV, VVR, VVU, VVV with and
  without vm bit set)

Known limitations:
- Vector configuration will be set with vsetivli x0, AVL, eSEW, m1, ta, ma
- No tests for invalid configurations (that would trigger exceptions)

* Add support for Zvkb

This patch introduces support for Zvkb:
- vandn.[vv,vx]
- vbrev8.v
- vclmul.[vv,vx]
- vclmulh.[vv,vx]
- vrev8.v

Support for RV32 and RV64 is added, but both versions are identical.
