Salvador Díaz Fau 44896524e8 Improved keyboard and mouse support in FMXExternalPumpBrowser for MacOS 
Added X11 error handling functions to FMXExternalPumpBrowser2 demo for Linux.
Deleted FMXExternalPumpBrowser demo for Linux.
Added uCEFMacOSConstants and uCEFMacOSFunctions units for MacOS.
Replaced TThread.Queue for TThread.ForceQueue to avoid executing that method immediately in some cases.
