gh-126255: Ignore warning about JIT being deactivated when perf support is active in test_embed.InitConfigTests.test_initconfig_api (#126302)

Browse source 
Temporarily ignore warnings about JIT deactivation when perf support is active. 
This will be reverted as soon as a way is found to determine at run time whether the interpreter was built with JIT. Currently, this is not possible on Windows.
