Add an optional p_interpolation parameter to Image::resize_to_po2() and call it in GLES2 rasterizer storage with either INTERPOLATE_BILINEAR or INTERPOLATE_NEAREST depending on TEXTURE_FLAG_FILTER.

This is equivalent of #44445 that closes #44379 in 3.2.

I'm sure the commits that add the function and the doc update respectively could be unified.

And thanks for your first contribution to Godot!

Should be good to go once you squash the commits together. For simple changes like this we prefer one commit.

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.
