    ifcvt: Add support for conditional copysign

    This adds a masked variant of copysign.  Nothing very exciting just the
    general machinery to define and use a new masked IFN.

    Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

    Note: This patch is part of a testseries and tests for it are added in the
    AArch64 patch that adds supports for the optab.

    gcc/ChangeLog:

            PR tree-optimization/109154
            * internal-fn.def (COPYSIGN): New.
            * match.pd (UNCOND_BINARY, COND_BINARY): Map IFN_COPYSIGN to
            IFN_COND_COPYSIGN.
            * optabs.def (cond_copysign_optab, cond_len_copysign_optab): New.
