[xerces-c] Fix dependencies

[dg0yt]

Do not find libnsl:
The package doesn't use a single header from https://packages.debian.org/bookworm/amd64/libnsl-dev/filelist.
The alternative autotools buildsystem checks for the lib with regard to gethostbyname which is usually provided by libc, and checked separately in the CMake buildsystem.
Fixes #32170.

Add a default-feature network.

Updates dependency lookup and export - Fixes android builds.

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

halide:x86-windows seems to be a baseline regression:

FTR it fails to run a tool which it builds:
