feat(ext/node): embed std/node into the snapshot (#17724)
This commit moves "deno_std/node" in "ext/node" crate. The code is transpiled and snapshotted during the build process. During the first pass a minimal amount of work was done to create the snapshot, a lot of code in "ext/node" depends on presence of "Deno" global. This code will be gradually fixed in the follow up PRs to migrate it to import relevant APIs from "internal:" modules. Currently the code from snapshot is not used in any way, and all Node/npm compatibility still uses code from "https://deno.land/std/node" (or from the location specified by "DENO_NODE_COMPAT_URL"). This will also be handled in a follow up PRs. --------- Co-authored-by: crowlkats <crowlkats@toaxl.com> Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com> Co-authored-by: Yoshiya Hinosawa <stibium121@gmail.com>
