Port File System APIs in Deno namespace to @std/fs

[kt3k]

We aim to make @std/fs cross-runtime (ref #4313). To achieve that we need to port FS APIs from Deno namespace (with Node.js compatibility)

• Deno FS APIs https://docs.deno.com/api/deno/file-system
• deno-shim https://github.com/denoland/node_shims/tree/main/packages/shim-deno/src/deno/stable/functions

Classes

• FsFile

Functions

• chmod
• chmodSync
• chown
• chownSync
• copyFile
• copyFileSync
• create
• createSync
• link
• linkSync
• lstat feat(fs/unstable): add fs.lstat #6276
• lstatSync feat(fs/unstable): add statSync and lstatSync #6300
• makeTempDir
• makeTempDirSync
• makeTempFile
• makeTempFileSync
• mkdir
• mkdirSync
• open
• openSync
• readDir
• readDirSync
• readFile
• readFileSync
• readLink
• readLinkSync
• readTextFile
• readTextFileSync
• realPath
• realPathSync
• remove
• removeSync
• rename
• renameSync
• stat feat(fs/unstable): add fs.stat #6258
• statSync feat(fs/unstable): add statSync and lstatSync #6300
• symlink
• symlinkSync
• truncate
• truncateSync
• umask
• utime
• utimeSync
• watchFs
• writeFile
• writeFileSync
• writeTextFile
• writeTextFileSync

shim-deno package already implements Node.js compatible Deno APIs. We can borrow the code from there for the Node.js compatibility part https://github.com/denoland/node_shims/tree/main/packages/shim-deno
