Add crypto to Polyfills improving Blueprint compatibility for Node (#…

## What is this PR doing?
It imports the native library `crypto` and makes it globally available
in the runtime.

## What problem is it solving?

When using blueprints that install plugins or themes, it generates a
random folder using
[`crypto`](https://developer.mozilla.org/en-US/docs/Web/API/Crypto)`.
That library is available in the browsers by default, but for node we
need to import it.

Note that it do not install any dependency since Crypto is already built
in NodeJS, but it's not imported by default.
I decided to use [`node:crypto`](https://nodejs.org/api/webcrypto.html)
which has `webcrypto` and will be a better match. It's available sine
Node v15.

The other alternative is normal
[crypto](https://nodejs.org/api/crypto.html)
https://nodejs.org/docs/latest-v14.x/api/crypto.html, which also has
`crypto.randomUUID`. It's available since Node v14.

## How is the problem addressed?

It adds a new Polyfill for crypto.

## Testing Instructions

1. Comment the first line `import './crypto';` on
`packages/php-wasm/node-polyfills/src/lib/crypto.spec.ts`
2. Run `npx nx test php-wasm-node-polyfills`
3. Observe the tests fail
4. Uncomment first line `import './crypto';` on
`packages/php-wasm/node-polyfills/src/lib/crypto.spec.ts`
5. Run `npx nx test php-wasm-node-polyfills`
6. Observe the tests pass
