    Better hints when RTS options not available (Trac #9579)
    
    This patch provides user with a better hint when most RTS options
    are not available (not compiled with `-rtsopts`).
    
    A new field "rtsOptsEnabled" is added into RtsFlags.MiscFlags to
    tell the availablity of RTS options.
    
    Some concerns:
    * Unlike other flag fields in "libraries/base/GHC/RTS/Flags.hsc",
      "RtsOptsEnabled" is defined in "includes/RtsAPI.h" and lacks
      constant macros. Therefore In "GHC.RTS", "RtsOptsEnabled" simply
      derives Enum instance and reads as of type "CInt".
    
    * There are other ways to change RTS options (e.g. `-with-rtsopts`),
      but it might be too verbose to mention.
    
    Test Plan: validate
