fix: work around gcc-4.8 bug in disjunction

See https://godbolt.org/z/i7-AmM for a repro of the bug.

I realize that Abseil no longer supports gcc 4.8 officially
(https://abseil.io/docs/cpp/platforms/platforms), but Cloud C++ still supports
gcc 4.8 officially, and so it would be nice to get this simple fix in.

Change spelling of internal detail from `Invoke`/`InvokeT` to `invoke`/`invoke_result_t`.

This matches the spelling of the C++17 standard library names that perform the same operations.
