Zvk: extensions parsing
Zvk is the short name for the Vector Cryptography Instruction
Set Extension Specification being defined at
<https://github.com/riscv/riscv-crypto/tree/master/doc/vector>.
This commit adds support for parsing/enabling the Zvk extensions
(Zvbb, Zvbc, Zvkg, Zvkned, Zvknha, Zvknhb, Zvksed, Zvksh, Zvkt)
and the combo extensions (Zvkn, Zvknc, Zvkng, Zvks, Zvksc, Zvksg).
This is an early commit in a series implementing Zvk. No instructions
are actually defined here, only infastructure that will
support the coming extensions.
The encodings for Zvk instructions have some conflicts with Zpn
encodings. This commit marks those Zpn instructions as overlapping,
and adds checks to error out if conflicting extensions are enabled.
