fix(profiling-ffi): Windows extern statics need __declspec(dllimport)

[morrisonlevi]

What does this PR do?

On the FFI headers on windows, this attends to replace "extern " with "extern __declspec(dllimport) ".

Motivation

These static variables result in a crash if you use them when they don't have __declspec(dllimport) .

Additional Notes

This went unfound because none of the examples run on Windows in CI. I am planning to look into running these as part of CI (this is in draft still).

How to test the change?

Build and note you don't get a crash anymore when using these static vars on Windows 😆
