Add alternative shortcut for Align Transform to View in the 3D editor

The new shortcut is Ctrl + Alt + Numpad 0 and is the one listed
in the 3D viewport's Perspective menu (since PopupMenu accelerators
display the first shortcut only). This shortcut matches Blender
and avoids conflicts with the GeForce Experience overlay, which
defaults to Ctrl + Alt + M.

Ctrl + Alt + M is still defined as an alternative default,
so that existing workflows are not impacted.
