COMP: Remove throw() exception specification from ~OpenCLCompileError()
COMP: Remove throw() exception specification from ~OpenCLCompileError()

Old-style `throw()` exception specifications are deprecated with C++11, and removed with C++20.

Destructors are `noexcept` by default now, with C++11, so it is not necessary to add an explicit exception specification anyway.
