Fix compatibility with new mods which use the C runtime of soku

This commit lets mods be loaded after the C runtime is initialized but
before other static objects of soku are constructed.

- Soku2 probably hooks constructors of static objects of soku. So it
  is too late to load Soku2 after these constructors are called.
- Some new mods depend on the C runtime of soku. So they should be
  loaded after the C runtime of soku is initialized.

`SetUnhandledExceptionFilter` is now called before mods are loaded, so
that mods can easily get the unhandled exception filter of SWRSToys and
set their own ones when being initialized.
