640fe94354 src,test: support dynamically linking OpenSSL 3.0
This commit enables node to dynamically link against OpenSSL 3.0.

The motivation for opening this PR even though OpenSSL 3.0 has not been
released yet is to allow a nightly CI job to be created. This will
allow us stay on top of changes required for OpenSSL 3.0, and also to
make sure that changes to node crypto do not cause issues when linking
to OpenSSL 3.0.

The asan checks don't play well currently with persistent secure
heap allocations.

crypto: implement basic secure heap support
Adds two new command line arguments:

* `--secure-heap=n`, which causes node.js to initialize
  an openssl secure heap of `n` bytes on openssl initialization.
* `--secure-heap-min=n`, which specifies the minimum allocation
  from the secure heap.
* A new method `crypto.secureHeapUsed()` that returns details
  about the total and used secure heap allocation.

The secure heap is an openssl feature that allows certain kinds
of potentially sensitive information (such as private key
BigNums) to be allocated from a dedicated memory area that is
protected against pointer over- and underruns.

The secure heap is a fixed size, so it's important that users
pick a large enough size to cover the crypto operations they
intend to utilize.

The secure heap is disabled by default.
