swung0x48 3049c4b82b [Fix] (ShaderTranspiler): stop blanking block comments in the source handed to glslang ...

- BlankBlockComments replaced comment chars with spaces but preserved interior newlines, so a block comment spanning a newline inside a #define truncated the macro body (VALUE became empty)
- glslang has a conformant preprocessor and collapses a block comment to one space across newlines, so the delivered source now keeps comments intact and lets glslang handle them
- Fixes KHR-GL3x.shaders.preprocessor multiline_comment_define / redefine_object_multiline_comment / function_redefinition_3 (6 cases, both devices)
- FilterUnsupportedGpuShaderInt64 relied on the blanking to skip commented-out #extension lines; it now masks comments locally (MaskCommentsAndQuotedText) like the sibling passes, collecting edits and applying them back-to-front
- conditional_inclusion.basic_2 (defined() via macro expansion) stays failing by design: glslang rejects it as UB and working around it would mean re-running preprocessing MobileGL defers to glslang

SpirvPasses

[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
