Add interpolation parameter to resize_to_po2()

Browse Source 
Image::resize_to_po2() now takes an optional p_interpolation parameter
that it passes directly to resize() with default value INTERPOLATE_BILINEAR.

GLES2: call resize_to_po2() with interpolate argument

Call resize_to_po2() in GLES2 rasterizer storage with either
INTERPOLATE_BILINEAR or INTERPOLATE_NEAREST depending on TEXTURE_FLAG_FILTER.

This avoids filtering issues with non power of two pixel art textures.
See #44379
