Fix INLINE pragmas in desugarer

In #19969 we discovered that GHC has has a bug *forever* that means it
sometimes essentially discarded INLINE pragams.  This happened when you have
* Two more more mutually recursive functions
* Some of which (presumably not all!) have an INLINE pragma
* Completely monomorphic.

This hits a particular case in GHC.HsToCore.Binds.dsAbsBinds, which was
simply wrong -- it put the INLINE pragma on the wrong binder.

This patch fixes the bug, rather easily, by adjusting the
no-tyvar, no-dict case of GHC.HsToCore.Binds.dsAbsBinds.

I also discovered that the GHC.Core.Opt.Pipeline.shortOutIndirections
was not doing a good job for

    {-# INLINE lcl_id #-}
    lcl_id = BIG

    gbl_id = lcl_id

Here we want to transfer the stable unfolding to gbl_id (we do), but
we also want to remove it from lcl_id (we were not doing that).
Otherwise both Ids have large stable unfoldings.  Easily fixed.
Note [Transferring IdInfo] explains.
