Fix keyboard layout icon in taskbar notification area. JIRA issue: CORE-11700, CORE-2699, CORE-18546
- Call ActivateKeyboardLayout to select the keyboard layout correctly.
- Modify WM_INPUTLANGCHANGEREQUEST parameter.
- Modify BroadcastSystemMessageW parameter.
- Revert Taskbar Notification Area MA_NOACTIVATE HACK 8344291 . This fixes Context Menu display.
- Load the "IME File" value and set the IME icon if necessary.
- Correctly implement global hooks.
Addendum to commits 5f4bb73e and c6ccb92b.
- GetLocaleInfo() returns an int, not a bool: makes it clear in the test.
- No need to use StringCchCopy() to just initialize two chars to the
same value.
- The question about the test in https://github.com/reactos/reactos/pull/4723#discussion_r981331634
was meant to discover that CreateDIBSection() was unnecessary, since
the very original code (before commit 0991cedc) did not use it and was
working fine in that regard. The simple fix was to use GetDC(NULL).
- Use SM_CXSMICON/SM_CYSMICON metrics for the KBSWITCH indicator as well.
- Override the font size obtained from SPI_GETICONTITLELOGFONT with a
known one (allows to get a correct indicator even if the user font
is very large).
- Do the initialization in such a way that in case SPI_GETICONTITLELOGFONT
or CreateFontIndirect fails, we always fall back to the default stock
font that is ensured to always exist.
- Initialize *all* the fields of the IconInfo structure.
- Do the same behaviour as input.dll in getting indicator text.
- Use full color DIB (device-independent bitmap) to improve icon.
- Use SPI_GETICONTITLELOGFONT for font.

Alt+Shift is a useful key combination to switch the current keyboard layout. CORE-11737
- Add ID_NEXTLAYOUT command to kbswitch.
- Send command ID_NEXTLAYOUT to kbswitch on Alt+Shift key combination in WM_SYSKEYDOWN handling of IntDefWindowProc function.
- Make IntFindWindow a non-static function.
The current Shift+Alt handling is buggy. The keyboard won't work frequently.
It dislikes system-side Alt (VK_MENU) key handling.
It seems like Shift+Alt handling should be in kernel.
