metal: allow unequal size attachments. OpenGLES3.0 allows FBO with attachments that have unequal size. In Metal, an FBO is represented by a render pass pipeline, which is created using MTLRenderPassDescriptor descriptor. The render pass can have color attachments as well as depth and stencil attachments. Those individual attachments must have a texture attached, which works as a buffer. However, the documentation does not specify any dimension restrictions for those textures. Test: verify the FramebufferTest_ES3.AttachmentsWithUnequalDimensions passes. Test2: made a simple metal app that renders using an offscreen render pass pipeline to a texture that has size of 32x16 with a depth buffer attached (size of 16x32) and verified the pixels on that. The content outside the common area had undefined pixel data.
