This PR moves all getValidatedFd calls to C++. Improves error path performance by ~17-42%.

It is semver-major, and would be a very disruptive change, especially if it happens incrementally. It's been a general rule for a long time in Node.js that validation happens synchronously.

See also #49970, which is blocked on the same problem as far as I am aware.

@mcollina @tniessen @targos I've updated the PR to remove server-major changes. We now validate only on sync call paths. This change will also allow us to move async function to C++ and potentially eliminate the usage of FSReqWrap so that we can throw the errors synchronously from C++.
