Move hardcoded build tags and ldflags from Makefile, Dockerfile, CI
workflows, and local build scripts into canonical files under release/:

- release/DEFAULT_BUILD_TAGS_WINDOWS (includes with_purego)
- release/DEFAULT_BUILD_TAGS_OTHERS (no with_naive_outbound)
- release/LDFLAGS (shared linker flags)

We mistakenly believed that `libresolv`'s `search` function worked correctly in NetworkExtension, but it seems only `getaddrinfo` does.
This commit changes the behavior of the `local` DNS server in NetworkExtension to prefer DHCP, falling back to `getaddrinfo` if DHCP servers are unavailable.
It's worth noting that `prefer_go` does not disable DHCP since it respects Dial Fields, but `getaddrinfo` does the opposite. The new behavior only applies to NetworkExtension, not to all scenarios (primarily command-line binaries) as it did previously.
In addition, this commit also improves the DHCP DNS server to use the same robust query logic as `local`.
