Vulkan:Allow same-named var in nested scope ESSL 1.00 spec allows for variable with same name to override outer variable inside of a nested scope. This change adds new scope to symbol table inside of a function defintion, but after function parameters for ESSL 1.00 shaders (but not webGL). This prevents an error while parsing. This also includes some new code in translator to rename any vars that are redefined between the function body and the function parameters. This prevents an error later on when the translated shader is then parsed as a desktop GLSL version.
