Metal: fix max point size and RGB565 renderbuffer bug. - Max point size is set to 64, since this is the max size observed. It is not 511 as https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf claims. - RGB565 is emulated on macOS by RGBA, needs to disable alpha write for this format. This was already done for TextureMtl, but wasn't for RenderBufferMtl. - Also enable true non-power-of-two textures support (OES_texture_npot). This was technically already supported, just that the extension wasn't advertised yet. - New Test: FramebufferFormatsTest.RGB565Renderbuffer Bug: angleproject:4816 Bug: angleproject:2634 Change-Id: Ie7e3efb4cb29bb9a3fd706c26e2b50b42ff3f6be Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2281797 Commit-Queue: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>
