[EXPLORER] menu flickery improvement

Hello,
this is my first time in jira, so please don't worry about mistakes.
I have look over the ros code for 0.4.14 in file:
\base\shell\explorer\startmnusite.cpp

at line: 125  (nearly at:

virtual HRESULT STDMETHODCALLTYPE AppendMenu(
OUT HMENU phMenu)*

I replace, and add following code:

...

static int flag = 0;

if (!flag) {

   flag = 1;

   *phMenu = LoadPopupMenu(hExplorerInstance,

    MAKEINTRESOURCEW(IDM_STARTMENU));

  hMenu = *phMenu;

  if (hMenu == NULL)

  return E_FAIL;

}

...

this reduce the flikkery of start-menue items to some cycles down.

tested under Windows 11, Virtual Box, Version 6.1
