    Fix PR 106690: enable effective_target_bswap for RISCV targets with ZBB
enabled by default

    While looking for testcases to quickly test, I Noticed that
    check_effective_target_bswap was not enabled for riscv when
    ZBB is enabled. This patch checks if ZBB is enabled when
    targeting RISCV* for bswap.

    OK? Ran the testsuite for riscv32-linux-gnu both with and without ZBB
enabled.

            * lib/target-supports.exp (check_effective_target_bswap):
            Return true if riscv and ZBB ISA extension is enabled.
