Given that FSReqPromise does not inherit from FSReqWrap, FSReqWrap
should be renamed FSReqCallback to better describe what it does.
First of a few upcoming `fs` refactorings :)

A small refactor – this removes one layer of pointer indirection.
(The performance gain is likely negligible, the main point here
being that this encapsulates libuv request management a bit more.)

Since libuv 1.21.0, pipes on Windows support `writev` on the
libuv side.
This allows for some simplification, and makes the `StreamBase`
API more uniform (multi-buffer `Write()` is always supported now,
including when used by other non-JS consumers like HTTP/2).

In the document for fs, there are several functions that state "No
arguments other than a possible exception are given to the completion
callback." (ex> fs.access, fs.chmod, fs.close, ..)
But, the functions are invoking the callback with two parameters (err,
undefined)
It causes problems in using several API like
[async.waterfall](https://caolan.github.io/async/docs.html#waterfall).

- Instead of storing a pointer whose type refers to the specific
subclass of `BaseObject`, just store a `BaseObject*` directly.
This means in particular that one can cast to classes along
the way of the inheritance chain without issues, and that
`BaseObject*` no longer needs to be the first superclass
in the case of multiple inheritance.
In particular, this renders hack-y solutions to this problem (like
ddc19be6de1ba263d9c175b2760696e7b9918b25) obsolete and addresses
a `TODO` comment of mine.
- Move wrapping/unwrapping methods to the `BaseObject` class.
We use these almost exclusively for `BaseObject`s, and I hope
that this gives a better idea of how (and for what) these are used
in our code.
- Perform initialization/deinitialization of the internal field
in the `BaseObject*` constructor/destructor. This makes the code
a bit more obviously correct, avoids explicit calls for this
in subclass constructors, and in particular allows us to avoid
crash situations when we previously called `ClearWrap()`
during GC.
This also means that we enforce that the object passed to the
`BaseObject` constructor needs to have an internal field.
This is the only reason for the test change.
- Change the signature of `MakeWeak()` to not require a pointer
argument. Previously, this would always have been the same
as `this`, and no other value made sense. Also, the parameter
was something that I personally found somewhat confusing
when becoming familiar with Node’s code.
- Add a `TODO` comment that motivates switching to real inheritance
for the JS types we expose from the native side. This patch
brings us a lot closer to being able to do that.
- Some less significant drive-by cleanup.
Since we *effectively* already store the `BaseObject*` pointer
anyway since ddc19be6de1ba263d9c175b2760696e7b9918b25, I do not
think that this is going to have any impact on diagnostic tooling.

In the async case, if the buffer was copied instead of being moved
then the buf will not get deleted after the request is done.
This was introduced when the FSReqWrap:: Ownership was
removed in 4b9ba9b, and ReleaseEarly was no longer called upon
destruction of FSReqWrap.
Create a custom Init function so we can use the MaybeStackBuffer in
the FSReqBase to copy the string in the async case. The data will
then get destructed when the FSReqBase is destructed.

When the async uv_fs_* call errors out synchronously in AsyncDestCall,
the after callbacks (e.g. AfterNoArgs) would delete the req_wrap
in FSReqAfterScope, and AsyncDestCall would set those req_wrap to
nullptr afterwards. But when it returns to the top-layer bindings,
the bindings all call `req_wrap->SetReturnValue()` again without
checking if `req_wrap` is nullptr, causing a segfault.
This has not been caught in any of the tests because we usually do a
lot of argument checking in the JS layer before invoking the uv_fs_*
functions, so it's rare to get a synchronous error from them.
Currently we never need the binding to return the wrap to JS layer,
so we can just call `req_wrap->SetReturnValue()` to return undefined
for normal FSReqWrap and the promise for FSReqPromise in AsyncDestCall
instead of doing this in the top-level bindings.
