Avoid creating GrGLPath to the resource cache when creating GrGLPathRanges

Do not create a GrGLPath when loading glyphs with the driver and creating
GrGLPathRange based on those. The path would be inserted to the GPU
resource cache and then immediately be released.

Instead, just init the first path object of the path range as the
template.
