[Feat] (ShaderTranspiler, DirectGLES): emulate noperspective on GLES devices lacking GL_NV_shader_noperspective_interpolation - EmulateNoPerspectivePass pre-multiplies each NoPerspective output by gl_Position.w in the vertex stage and recovers each input via gl_FragCoord.w in the fragment stage (exact screen-linear L = P(a*w)*gl_FragCoord.w, handling whole-variable and component/access-chain reads, scalar and vector varyings), forces highp on emulated varyings, and strips what it cannot emulate; replaces the smooth-strip fallback so no NV extension is ever required. Restricts the vertex pre-multiply to the entry function so a non-inlined helper cannot double-scale
