Increase page size for azure windows agents?

[h-vetinari]

After often encountering

OSError: [WinError 1455] The paging file is too small for this operation to complete

in conda-forge/numpy-feedstock#237 & many other pull requests (for numpy), I decided to have a quick look at what's behind that.

Stumbling over this discussion (regarding GH Actions), someone noted:

I’ve investigated this issue and the problem is that Windows decides to create a single page file on the D:\ drive, which has only 14 GB, and by default it allocates only 1/8th of the volume size, or about 1.75 GB. This is a very small page file by modern standards and many applications will fail.

How about adding an option (or step) to the ci-setup that allows setting the page file size? It seems to be possible for GHAs - someone published an action for it (it's MIT licensed so we could even reuse some of that code).

PRs welcome. I don't think we need an option for this. Doing this unconditionally makes sense.

Wait, maybe only if CONDA_BLD_PATH is set to C://bld//

Core of such a PR would IMO be copying SetPageFileSize.ps1 and calling it from run_conda_forge_build_setup_win.bat appropriately (i.e. if-cond & params) - would you want that in recipe/ or recipe/conda_forge_ci_setup or elsewhere?

[isuruf]

In recipe is fine.
