T4 Wire defines for IIMPLEMENT...

Added defines like we have for T3.x/LC
That it implements Wire, Wire1, Wire2,

So that programs that care can build using without having to special case T4

WireIMXRT.h

 
 #define BUFFER_LENGTH 32
 //#define WIRE_HAS_END 1
+#define WIRE_IMPLEMENT_WIRE
+#define WIRE_IMPLEMENT_WIRE1
