librpc/idl: Remove DCOM and WMI IDL
As hinted in
f2416493c0c779356606aebf0aceca8fa416b55c the DCOM and WMI
IDL is now unused. These generate code with PIDL, costing a small
amount of build time but more importantly are fuzzed, which costs an
ongoing amount of CPU time as oss-fuzz tries to find parsing issues.
We do not need to continue this waste, and these can be restored
if this effort is ever to start again.
