Subject: [PATCH] Patch absl so that it doesn't disable important VC++ warnings
 (#10836)

This PR is just for making onnxruntime passing Binskim rules.

Below is how I made it:

git clone absl repo, checkout the version we are using
Then apply our patch file
Make modifications
Regenerate the patch file by "git diff > C:\src\onnxruntime\cmake\patch\xxx.patch"
Then submit the change to our repo
You will need to repeat the steps when you need to advance the absl commit or add more changes to it.
