Routine Description:
This routine implements the GUI prompt for credentials
Arguments:
DoingCommandLine - TRUE if prompting is to be done via the command line
FALSE if prompting is to be done via GUI
delayCredentialWrite - TRUE if the credential is to be written only upon confirmation.
FALSE, if the credential is to be written now as a session credential then
morphed to a more persistent credential upon confirmation.
This field is ignored if Flags doesn't specify CREDUI_FLAGS_EXPECT_CONFIRMATION.
credCategory - This is the subset of the "flags" parameter defining the category of
the credential.
