Restore the Buffer.isBuffer() check to avoid unnecessary Buffer.from()
calls when the input is already a Buffer. This improves performance
by 30-50% for buffer-heavy UDP operations.
Includes benchmark test for fixBufferList function to verify the
performance improvements across different data types and chunk sizes.

This improves dgram performance by avoiding unnecessary async
operations.
One issue with this commit is that it seems hard to actually create
conditions under which the fallback path to the async case is
actually taken, for all supported OS, so an internal CLI option
is used for testing that path.
Another caveat is that the lack of an async operation means
that there are slight timing differences (essentially `nextTick()`
rather than `setImmediate()` for the send callback).

Code in benchmark directory sometimes uses `function () {}` for
anonymous callbacks and sometimes uses `() => {}`. Multi-line arrays
sometimes have a trailing comma and sometimes do not. Update to always
use arrow functions for anonymous callbacks and trailing commas for
multiline arrays.

`benchmark/dgram/bind-params` exits with an error frequently in its
current form because no error handler is applied. Add no-op error
handlers to avoid the problem.

Remove variables that are assigned but never used.
(This was missed by the linter in previous versions of ESLint but is
flagged by the current version. Updating the linter is contingent on
this change or some similar remedy landing.)

In the hopes of soon having the benchmark code linted, this change
groups all the likely non-controversial lint-compliance changes such as
indentation, semi-colon usage, and single-vs.-double quotation marks.
Other lint rules may have subtle performance implications in the V8
currently shipped with Node.js. Those changes will require more careful
review and will be in a separate change.
