This removes all internal calls to the deprecated `_extends()`

As it is, `readFile` always reads from the current position of the file,
if a file descriptor is used. But `writeFile` always writes from the
beginning of the file.
This patch fixes this inconsistency by making `writeFile` also to write
from the current position of the file when used with a file descriptor.

82bdf8fba2 fixed an issue by silently modifying the `start`
option for the case when only `end` is passed, in order to perform
reads from a specified range in the file.
However, that approach does not work for non-seekable files, since
a numeric `start` option means that positioned reads will be used
to read data from the file.
This patch fixes that, and instead ends reading after a specified
size by adjusting the read buffer size.
This way we avoid re-introducing the bug that 82bdf8fba2 fixed,
and align behaviour with the native file stream mechanism
introduced in https://github.com/nodejs/node/pull/18936 as well.

Added a test to ensure input validation for FD and mode for fs.fchmod.
Removed check for values lower than 0 for `mode` as it's already checked
by `validateUint32`.

Problem:
Node implements fs.readFile as:
- a call to stat, then
- a C++ -> libuv request to read the entire file using the stat size
Why is this bad?
The effect is to place on the libuv threadpool a potentially-large
read request, occupying the libuv thread until it completes.
While readFile certainly requires buffering the entire file contents,
it can partition the read into smaller buffers
(as is done on other read paths)
along the way to avoid threadpool exhaustion.
If the file is relatively large or stored on a slow medium, reading
the entire file in one shot seems particularly harmful,
and presents a possible DoS vector.
Solution:
Partition the read into multiple smaller requests.
Considerations:
1. Correctness
I don't think partitioning the read like this raises
any additional risk of read-write races on the FS.
If the application is concurrently readFile'ing and modifying the file,
it will already see funny behavior. Though libuv uses preadv where
available, this doesn't guarantee read atomicity in the presence of
concurrent writes.
2. Performance
Downside: Partitioning means that a single large readFile will
require into many "out and back" requests to libuv,
introducing overhead.
Upside: In between each "out and back", other work pending on the
threadpool can take a turn.
In short, although partitioning will slow down a large request,
it will lead to better throughput if the threadpool is handling
more than one type of request.
