StripLayer: Optimize shared_ptr move

StripDesignPtr is a shared pointer so this simple construction is doing needless reference counting (expensive memory locking).

MuonGMR4::StripLayer::StripLayer(GeoModel::TransientConstSharedPtr<StripDesign>) [base object constructor]: # @MuonGMR4::StripLayer::StripLayer(GeoModel::TransientConstSharedPtr<StripDesign>) [base object constructor]
        mov     rax, qword ptr [rsi]
        mov     qword ptr [rdi], rax
        mov     rax, qword ptr [rsi + 8]
        mov     qword ptr [rdi + 8], rax
        test    rax, rax
        je      .LBB0_4
        mov     rcx, qword ptr [rip + __libc_single_threaded@GOTPCREL]
        cmp     byte ptr [rcx], 0
