Fix additional UAF in DirEntry building

fs.mitm: Fix UAF in every DirEntry processed. ...

How on earth did this code ever work?

fs_istorage: Default IStorage destructor in cpp ...

Prevents a -Wweak-vtables warning.

stratosphere: In-class initialize members ...

Same thing, less code, less boilerplate.

stratosphere: Use RAII for locks ...

This renames the Mutex class member functions so that the mutex types
satisfy Lockable.

This makes them usable with standard std::scoped_lock
and std::unique_lock, which lets us use RAII and avoids the need
for a custom RAII wrapper :)

pm: Fix missing include

stratosphere: Remove an unneeded constructor ...

domain_objects is already an array of empty std::shared_ptrs (since
std::shared_ptr has a sane default constructor).

fs.mitm: Save memory+time in sibling reconstruction via reverse iteration

fs.mitm: Optimize out remaining O(n^2) op. BotW is very fast.
