dev,generate-cgo: externalize cgo files gen into a seperate binary
Previously, we only needed to gen cgo files using `dev` so that was were that logic lived. Now, we need to gen cgo files outside dev to fix an issue with gcassert [see cockroachdb#65485]. This code change externalizes the code into a separate binary and let's `dev gen cgo` point to it. Release note: None Epic: None Informs cockroachdb#65485
