1. nb::handle: make bool conversion explicit to avoid ambiguity with int… …

   …eger conversions in derived types
   
   An `explicit operator bool()` can still be used in conditional tests without a cast (`if (h) { ... }`) and is a better match for the explicitness of, for example, `operator int()` in `nb::int_`. Without this change, if you write
   ```
   void fn(nb::int_ ival) {
       int i = ival;
       printf("%d\n", i);
   }
   ```
   then `fn(nb::int_(42))` will print 1. (Only implicit conversions are allowed by the initialization style used, so the implicit `operator bool` in `nb::handle` is eligible while the explicit `operator int` in `nb::int_` is not.)
