### Description
1. Move C/C++ deps' URLs to deps.txt, and download the dependencies from
Azure Devops Artifacts instead of github.
2. Add "EXCLUDE_FROM_ALL" keyword to the cmake external projects, so
that we only build the parts we need and avoid installing the 3rd-party
dependencies when people run `make install` in ORT's build directory.
However, at this moment cmake itself doesn't have the feature. So I
copied their code to cmake/external/helper_functions.cmake and modified
it.
This PR is split from #13523, to make that one smaller.
### Motivation and Context
1. Secure the supply chain
2. Make it be possible to automatically detect if ORT has an old
dependency that hasn't been updated from a long time.
