`fs.copyFile()` supports copy-on-write operation
if the underlying platform supports it by passing a mode flag.
This behavior was added in
a16d88d9e9.
This patch adds `mode` flag to `fs.cp()`, `fs.cpSync()`,
and `fsPromises.cp()` to allow to change their behaviors
to copy files.
This test case is based on the test case that was introduced
when we add `fs.constants.COPYFILE_FICLONE`.
a16d88d9e9.
This test strategy is:
- If the platform supports copy-on-write operation,
check whether the destination is expected
- Otherwise, the operation will fail
and check whether the failure error information is expected.

It turns out that even with startup snapshots, there is a non-trivial
overhead for loading internal modules. This patch makes the loading
of the non-essential modules lazy again.
Caveat: we have to make some of the globals lazily-loaded too,
so the WPT runner is updated to test what the state of the global
scope is after the globals are accessed (and replaced with the
loaded value).

The FS docs wrongfully indicated support for passing object with an own
`toString` function property to `FileHandle.prototype.appendFile`,
`FileHandle.prototype.writeFile`, `FileHandle.prototype.write`,
`fsPromises.writeFile`, and `fs.writeSync`. This commit fixes that, and
adds some test to ensure the actual behavior is aligned with the docs.
It also fixes a bug that makes the process crash if a non-buffer object
was passed to `FileHandle.prototype.write`.
