Fix JS_WIDESTRING to work with clang-cl
MSVC lexes L#macro_arg as a single wide string literal token, but
Clang and other C/C++ compliant lexers do not. There was already
a workaround to use implicit string concatenation for GCC, but there's
a simpler solution of token pasting the L onto the stringized macro
argument with 'L###macro_arg'. This works with Clang, GCC, and MSVC.
