feat: Make all stubs weak imports

[GrayJack]

Make all stubs weak. This makes modules not fail to load when a linked lib was not loaded yet.

This is benefitial mostly for plugins, as they are often loaded before all system modules were started. And CFW have API that allows to inject a module to be loaded as early as the second module the system loads; in this edge case, all modules but sysmem libraries ideally should be weak.

I also noticed that some stubs were with the version part as 0011 which is the system module version used on FW>=6.60 on some modules, this will cause any module linking to them to fail loading on firmware version <6.60 as the system checks the stubs version on load if the library module was already loaded (if the imports are below or equal to the loaded library version, the module fails to load). On the cases of library modules allowed to be loaded multiple instaces of the module, at least one loaded version must match the imported stub version. I did not test the case of a weak imported with version bigger than the version that will be loaded after, but my best guess is that some error will occur in this case as well. To avoid this, I put then all to zero on the SDK stubs.

since you requested a review: optically looks good now, but i cant comment on the change of the constants, as i dont really have an insight what the effect of changing them might cause.

This is a necessary change, specially for low level kernel development.
