  [RISCV][NFC] Remove hasStdExtCOrZca (#145139)

As of 20b5728b7b1ccc4509a316efb270d46cc9526d69, C always enables Zca, so
the check `C || Zca` is equivalent to just checking for `Zca`.

This replaces any uses of `HasStdExtCOrZca` with a new `HasStdExtZca`
(with the same assembler description, to avoid changes in error
messages), and simplifies everywhere where C++ needed to check for
either C or Zca.

The Subtarget function is just deprecated for the moment.
