win, build: generate .sln only when necessary 
When generating sln, store flags passed to configure. Next time, if
node.sln exists and configure flags match those stored, skip building
.sln files.

Adds forceprojgen vcbuild option to force .sln regeneration.

If this is only needed for L262 & L263, could this be moved there? Otherwise I can see this giving someone a headache in the future.

Can we rename the tmp file .used_configure_flags. I know this is not *nix, but git will exclude it by default, and Windows will at least group it together with the rest of the settings/temporary files.
