    arm: [MVE] Fix operands order in vbicq_f [PR122223]

    The operands of the floating-point version of vbicq were swapped, this
    patch fixes this.

    For this backport the testcase needs an adjustment: the code is less
    optimized than with gcc-15, so we still generate the 0.0f constant and
    a vbic instruction.  We actually check that the 0.0f constant is in
    the right vbic parameter.
