v8-fast-api-calls.h is no longer in headers archive #43619
Description
v8-fast-api-calls.h was included in the header archive for 15.x (and 14.x?), but it is no longer included as of v16.0: https://nodejs.org/download/release/v16.0.0/node-v16.0.0-headers.tar.gz
It would be nice to have this back so that native add-ons could properly use (and compile with) the new V8 fast call api (like Node does with process.hrtime).

This was a deliberate change under #37570 so cc @targos.

I assumed it was deliberate. Based on the thread, it sounds like they were on the fence about the fast api calls header, but it was considered a little bit too unstable. And this is fine, I've included a copy of the headers file for now in my package, but hopefully it would be a priority to include the fast api calls header soon, as it stabilizes.

Only people from the V8 team can tell us when they think it's stable. FWIW I had to adapt Node.js to a breaking change less than a month ago: 4723ff1
