1ES enforced CodeQL times out the Windows leg

[premun]

Context

After the switch onto the 1ES Pipeline Templates, an unskippable CodeQL check that runs every 72 hours will slow down the Windows build until it times out.
Example https://dev.azure.com/dnceng/internal/_build/results?buildId=2413626&view=results

Solution

Figure out what to do about this:

• Increase the time out
• Tune the scan (?)
• Run the scan in a weekly pipeline only
