This patch re-enables custom V8 snapshot integration. Also renames
the experimental configure switch from `--with-node-snapshot`
to `--without-node-snapshot` to be consistent with`--without-snapshot`
which is used for the default V8 snapshot.

This was added in 16f86d6c57, based on
the assumption that otherwise, the memory behind `ArrayBuffer`
instances could be moved around on the heap while native code
holds references to it.
This does not match what V8 actually does (and also did at the time):
- The option/build variable was about always only about TypedArrays,
not ArrayBuffers. Calls like `new ArrayBuffer(4)` call into C++
regardless of the option value, but calls like `new Uint8Array(4)`
would not call into C++ under V8 defaults.
- When first accessing a heap-allocated TypedArray’s `ArrayBuffer`,
whether that is through the JS `.buffer` getter or the C++
`ArrayBufferView::Buffer()` function, a copy of the contents is
created using the ArrayBuffer allocator and stored as the
(permanent, unmovable) backing store.
As a consequence, the memory returned by `ArrayBuffer::GetContents()`
is not moved around, because it is fixed once the `ArrayBuffer`
object itself first comes into explicit existence in any way.
Removing this build option significantly speeds up creation of typed
arrays from JS:

The performance gains effect are undone once native code accesses
the underlying ArrayBuffer, but then again that a) does not happen for
all TypedArrays, and b) it should also make sense to look into using
`ArrayBufferView::CopyContents()` in some places, which is made
specifically to avoid such a performance impact and allows us to
use the benefits of heap-allocated typed arrays.

Make node-report part of core runtime because:
1. When enabled, node-report significantly helps root cause various
types of problems, including support issues sent to the various repos
of the Node.js organization.
2. The requirement of explicitly adding the dependency to node-report
in user applications often represents a blocker to adoption.
Major deviation from the module version of the node-report is that the
report is generated in JSON format, as opposed to human readable text.
No new functionalities have been added, changes that are required for
melding it as a built-in capability has been affected on the module
version of node-report (https://github.com/nodejs/node-report)

This commit introduces a new configuration flag named
--openssl-is-fips which is intended to be used when linking against
an OpenSSL library that is FIPS compatible.
The motivation for this is that Red Hat Enterprise Linux 8 (RHEL8)
comes with OpenSSL 1.1.1 and includes FIPS support, and we would
like to be able to dynamically link against this version and also have
FIPS features enabled in node, like would be done when statically
linking and using the --openssl-fips flag.
The suggestion here is to introduce a new flag:
$ ./configure --help
...
--openssl-is-fips specifies that the shared OpenSSL version is FIPS
compatible
This flag could be used in combination with the shared-openssl flag:
$ ./configure --shared-openssl ---openssl-is-fips
This will enable FIPS support in node and the runtime flags will be
availalbe to enable FIPS (--enable-fips, --force-fips).

It does disable SLOW_DCHECKS, but at the advice of the V8 team, those
are more important for deep V8 debugging.
Override is configurable with `./configure --v8-non-optimized-debug`.
