libc-wasi: add missing pointer validations to socket functions (#4611) (#4665)

Browse Source 
* libc-wasi: add missing pointer validations to socket functions (#4611)
cf. https://github.com/bytecodealliance/wasm-micro-runtime/issues/4463
the fix for sock_addr_resolve is incomplete.
cf. https://github.com/bytecodealliance/wasm-micro-runtime/issues/4610

* Sync from main branch
  - wasi_sock_recv doesn't use src_addr
  - check src_addr before coverting

* CI: use windows-2022 image for now (#4633)

github is currently rolling out windows-2025 image.
for some reasons, the "path_symlink_trailing_slashes" test case in
wasi testsuite fails on windows-2025 image.
someone familar with windows need to investigate what was the
key difference between 2022 and 2025.
until that happens, this commit makes our CI use windows-2022 image.
