TEMPFILE is the built-in way of SCons to use a response file for command lines that are too long. (cherry picked from commit 28b95ff)
Set `TEMPFILEARGESCFUNC`[1] to replace backslashes with forward slashes in paths. [1]: https://scons.org/doc/production/HTML/scons-user/apa.html#cv-TEMPFILEARGESCFUNC (cherry picked from commit 4542516)
It's not clear what is the actual max value that windows support, but despite their claim of it being 8191 we have been seeing failure with just 8150. (cherry picked from commit 395a4fc)

This PR cherry-picks PR #96407, PR #97188, and PR #97458, fixing issue #99710 in the Godot 4.3 branch. In general 4.3 is considered EOL, but buildsystem fixes are still valid to backport.
I have a large module which supports multiple Godot versions, all the way back to Godot 4.3. However, the module is now big enough that I am getting an error "The command line is too long" when compiling on Windows (it actually doesn't trigger on my machine, but it triggers on CI and on another person's machine, and I believe it's gotta be close to the limit on my machine too).
This PR cherry-picks those 3 PRs to fix this problem. I have tested that this works, the CI successfully compiles with these fixes.
Disclaimer: I am far from an expert on this specific code. The only thing I have done is perform the cherry-picks and test that this fixes the problem. I did not test every combination of the individual PRs to see which specific ones are needed to fix the problem, I just tested all of them in one go and it worked.
