[PATCH v5 0/3] MR8553: Draft: kernelbase: implement VirtualProtectFromApp

[Kareem Aladli (＠karim_adli)]

This implements the VirtualProtectFromApp function in kernelbase, which was previously a commented out stub.

Even though this function is meant for UWP apps, it is usable in desktop apps, as specified in [Windows documentation](https://learn.microsoft.com/en-us/windows/win32/api/memoryapi/nf-memoryapi-v...).

Fixes Wine-Bug: [https://bugs.winehq.org/show_bug.cgi?id=58482%5D(https://bugs.winehq.org/sho...)
