Add %sqlcontext to the list of %variables that Language Server knows about

[isc-solon]

In class methods defined as stored procedures [SqlProc], the system provides the variable %sqlcontext (of type %Library.ProcedureContext). Please add this to the list of %variables the Language Server knows about so #dim is no longer necessary for code completion for that %variable.

Thanks for opening this @isc-solon. Are there any others that I missed?

I couldn't think of any beyond the existing list.
