Add a test to check glReadPixels format and type In GLES 3.2 spec https://registry.khronos.org/OpenGL/specs/es/3.2/es_spec_3.2.pdf, section 16.1.2, it says the following glReadPixels type and format should work: The second is an implementation-chosen format from those defined in table 8.2... The values of format and type for this format may be determined by calling GetIntegerv with the symbolic constants IMPLEMENTATION_COLOR_READ_FORMAT and IMPLEMENTATION_COLOR_READ_TYPE, respectively. The implementation-chosen format may vary depending on the format of the selected read buffer of the currently bound read framebuffer. Add a test to check that when reading from the default framebuffer, using the format and type retrieved from IMPLEMENTATION_COLOR_READ_FORMAT and IMPLEMENTATION_COLOR_READ_TYPE works.
