feat: node os module

[Puellaquae]

Implement node os module in js, WasmEdge/WasmEdge#1535 .
Module name "os" has been used by quickjs, and in windows "node:os" is not a valid name, so I named "nodeos" temporarily.
os.constants and os.networkInterfaces() return empty data.
os.getPriority(), os.loadavg() and os.userInfo() return fake data.
os.cpus() is unimplemented and will throw error.
os.totalmem() always return 4294967296 (4GiB, as much as wasm32 can use) and os.freemem() is totalmem() - memory.size.

rename nodeos.js to os.js

rename nodeos.js to os.js

Will this name not conflict with this quickjs built-in os module?

[Puellaquae]

Or, should re-export built-in os module in os.js?

Oh, I forget it.

Line 369 in a471968

js_init_module_os(ctx, "os\0".as_ptr() as *const i8);

quickjs built-in os module is registered by this line.

modify it to js_init_module_os(ctx, "qjs:os\0".as_ptr() as *const i8); just ok.

I rebase my branch to latest main, rename nodeos.js to os.js, and re-export qjs:os in os.js.
