Clean up redundant initialization of gl_Position In case gl_Position is statically used in the input shader, setting the INIT_OUTPUT_VARIABLES flag will initialize gl_Position. Avoid redundant initialization of gl_Position in this case. Includes cleaning up memory management in InitOutputVariables_test: all the pool-allocated variables will be freed at the end of each test when the memory pool is cleared, so manual memory management is not needed. Also includes making the zero node check used in unit tests stricter so that the tests are more reliable and moving it to ShaderCompileTreeTest.h so that it can be reused in the future.
