[Fix] (MG_Backend/DirectGLES, MG_Util/ShaderTranspiler): make the uniform-block cross-stage precision fix surgical - revert the global SPVC ES highp-default options (they changed emission for EVERY fragment shader: sampling code that used to inherit the effective highp default was suddenly printed as explicit mediump, regressing KHR-GL3x.texture_repeat_mode NPOT mip cases on device) and instead strip RelaxedPrecision member decorations from uniform-block-reachable structs in a DirectGLES-only SPIR-V pass, so matched blocks declare identical (highp) member precision in both stages and every other shader keeps its previous emission byte-for-byte
