Subject: [PATCH] Explicitly create all sub-controls in
 wxPropertyGridManager::Create()

Instead of deferring creation of wxPropertyGrid and other controls
to EVT_SIZE handler we can create them when wxPropertyGridManager
is created and its initial size is known.
This way we can avoid using a trick with magic number used as a flag
to determine when to create all controls in OnResize().

Closes #24171.
