This removes the need to have xxd installed and provides a portable way to specify the name of the output array (xxd has an `-n` option for this, but it isn't present in older versions of xxd), which helps reduce the possibility of symbol conflicts in libretro builds and also prevents portability issues since the name of xxd's output array depends on the relative path to the input file, which can break if Meson changes the structure of the build directory or if the user sets the build directory to a different location. Also, this custom executable declares the array as const so that it goes into the read-only data section of the binary instead of the data section.
