[Bug]: Compile-time string format checking not working with MSVC

[gix]

Describe the issue

The compile-time string format checking of absl::StrFormat doesn't work when compiling with MSVC.

I've looked through the docs of StrFormat and the C++ support matrix and couldn't find any mention of this. That's a pretty big footnote to leave out. And since the implementation isn't standards-compliant and instead defers to compiler extensions, it doesn't look like this is gonna change anytime soon.

Steps to reproduce the problem

absl::StrFormat("%s", 1); compiles instead of erroring.
