* Avoid using WinHttpQueryDataAvailable, and use WinHttpReadData directly for better throughput.
* Add back new line at end of file.
* Reorder some lines for readability.
Part of https://github.com/Azure/azure-sdk-for-cpp/issues/1277, checking what types of warnings the CI emits.
Verified all SDK product `.cpp`, `.hpp`, `.txt`, and `.md` files, primarily focused on azure-core. They are all clean now. There are some exceptions that needs to be added for keyvault and storage, but they are false positives, so not a concern.

CSpell: Files checked: 188, Issues found: 0 in 0 files
> `cspell lint --config .vscode/cspell.json *.cpp */**/*.cpp`
CSpell: Files checked: 186, Issues found: 88 in 15 files (keyvault and storage false positives, or tests)

CSpell: Files checked: 646, Issues found: 328 in 69 files (most of these are in eng\docs\api\assets\style.css or eng/common)
Deprioritize and ignored the errors from the test files (including test resource json files), and `eng/common` since those need to be centrally fixed.
* Removed the `Azure::Core::Http::Request` ctor overload that takes both a `bodyStream` and a `bufferedDownload` boolean since it is not used anywhere.
* Add back the unit tests by making them friends.
* Add back line at end of file.
