target/riscv: Remove the W-form instructions from Zbs

Zbs 1.0.0 (just as the 0.93 draft-B before) does not provide for W-form
instructions for Zbs (single-bit instructions).  Remove them.

Note that these instructions had already been removed for the 0.93
version of the draft-B extention and have not been present in the
binutils patches circulating in January 2021.
