Use the GTest portability headers

Summary:
Switch all of the uses of `<gtest/gtest.h>` to `<folly/portability/GTest.h>`.

This is painful but necessary to get the tests to compile nicely under MSVC.

delete const rvalue reference ctor of folly::Function

Summary:
This code compiles and is causing stack overflow at runtime:

```
using F = folly::Function<void()>;
void foo(F);

F bar;
auto baz = [bar = std::move(bar)] {
  foo(std::move(bar));
};
baz();
```

The bug there is that `baz` is missing `mutable` keyword, so when
constructing argument for `foo`, `F(const F&&)` is called, which is selecting
`template <typename Fun> F(Fun&&)` (where `Fun = F const`) and we end up in
an infinite `F<Fun>(Fun&&) <-> F<Fun>(Fun&&, SmallTag|HeapTag)` cycle.

This diff transforms this easy-to-make-bug into compile-time error.
