Port some fixes from MarathonRecomp

[squidbus]

• Use big endian for XRTL_CRITICAL_SECTION fields. The current code assumes these are not accessed by the game, but they can be, for example in Sonic '06. I also added prefix and postfix operators to the big-endian wrapper to account for some of the current uses of these fields in projects.
• Fix image size for basic compressed XEX. The size from the security info was being used instead of the updated imageSize from the decompression process.
• Expose resource info in the Image output from Image::ParseImage. This makes it sufficient to use for loading the XEX when recomp starts instead of duplicating code.
• Fix compiler warnings about comparing uint32_t values to NULL in the recompiler.
