SpecBase: Remove usages of const_cast 

It's generally the case that mutexes are marked as mutable whenever they
need to be used within a const class context, given they don't directly
participate as a bitwise member of the class, but only transiently exist
so that synchronization operations can occur.

Given that, marking the member as mutable in this case makes sense.
