Use a new lexical context for sloppy-mode eval

In ES6, direct eval() in sloppy mode uses the enclosing function-level

This way we can greatly simplify the different variants of ToObject in
our codebase and make them more uniform and robust.  Adding a new
primitive doesn't require finding and changing all those places again,

Remove several grab-bag includes from the v8.h header.

This is the first step of turning the v8.h file into a normal header
instead of an include-the-world header. The new rule is that no other
header files are allowed to include v8.h, which is enforced by DEPS.

Also the number of includes inside the v8.h file has been drastically

objects-inl.h file.
