[FREELDR] Add the possibility to change the boot load options from TXTSETUP.SIF
at runtime from the boot selection menu or from FREELDR.INI. CORE-17350, CORE-9023 For a proper override of the options by new user options, specify the /SIFOPTIONSOVERRIDE switch in addition. Otherwise, user options are merged with those retrieved from TXTSETUP.SIF, with priority given to the former ones. - Update the documentation for the 'ReactOSSetup' OS type in the FREELDR.INI file template. - Use a different prompt in the custom boot options editor for the 'ReactOSSetup' OS type, with adequate explanation. - Get rid of the ReactOS-specific TXTSETUP.SIF 'DbgOsLoadOptions' value, and use instead the Windows-compatible 'SetupDebugOptions' value that is added to the other load options when debugging is to be enabled.
