target/riscv: redirect XVentanaCondOps to use the Zicond functions

The Zicond standard extension implements the same instruction
semantics as XVentanaCondOps, although using different mnemonics and
opcodes.

Point XVentanaCondOps to the (newly implemented) Zicond implementation
to reduce the future maintenance burden.

Also updating MAINTAINERS as trans_xventanacondops.c.inc.

target/riscv: Add XVentanaCondOps custom extension

This adds the decoder and translation for the XVentanaCondOps custom
extension (vendor-defined by Ventana Micro Systems), which is
documented at https://github.com/ventanamicro/ventana-custom-extensions/releases/download/v1.0.0/ventana-custom-extensions-v1.0.0.pdf

This commit then also adds a guard-function (has_XVentanaCondOps_p)
and the decoder function to the table of decoders, enabling the
support for the XVentanaCondOps extension.
