cc: Add a texture target to TextureMailbox.

Not all textures provided through TextureMailbox will be GL_TEXTURE_2D. When
the compositor consumes or produces mailboxes with other targets, it needs to
specify the appropriate target.

Tests:
ResourceProviderTest.TextureMailbox_GLTexture2D
ResourceProviderTest.TextureMailbox_GLTextureExternalOES
