Unrolled build for #152705

Rollup merge of #152705 - PaulDance:patches/skip-raw_attributes-doctest, r=joboet

Test(lib/win/proc): Skip `raw_attributes` doctest under Win7

The current doctest for `ProcThreadAttributeListBuilder::raw_attribute` uses `CreatePseudoConsole`, which is only available on Windows 10 October 2018 Update and above. On older versions of Windows, the test fails due to trying to link against a function that is not present in the kernel32 DLL. This therefore ensures the test is still built, but not run under the Win7 target.
