This PR intends to add support for .NET scripts that can extend ImHex's
functionality in a portable and cross-platform way.

This PR it just a hack to fix#1160 , it doesn't solve the underlying
problem.
It fixes the problem because by using execvp() directly, it avoids the
call to `sh` done with `system()`, which has a bug on Ubuntu 22.04 which
makes it i,compatibles with the glibc inside the AppImage.
It doesn't fix the underlying problem because the programs we call
themselves still link to the AppImage's libraries instead of the system
ones.
### Problem description
Currently, the providers use the method `isSavable()` to determine both
if they can use "Save" or "Save as".
This behaviour is problematic because some providers may need to be
saveable but not saveable as: for example the view provider. The
original provider may not allow to be saved.
### Implementation description
I separate these two behaviour by creating another function:
`isDumpable()`, that return true by default but can be overridden by the
provider to return false, if the provider should not be dumped in any
way.
### Additional things
While I was at it, I also marked "export" operations as needing the
"dumpable" flag. That way, we can't accidentally export the whole
address space of a process as base64.
I also added documentation for these some functions in Provider
This PR fixes some things about crash handling:
- when the terminate handler is called, immediately set it back to the
original one, so can't make a recursion if the crash-handling code fails
- Only save projects if the crash occured after Imhex finished startup
- do not update the project location when saving the crash backup file:
this will remove problems when `EventAbnormalTermination` is called
before `crashCallback()`
I also added a bit more documentation
