Chore: Enable warnings as errors on MSVC (#6456)

* tests: add Sanity test for SplitFilename83 fix test fix test * disable `C4715:not all control paths return a value` for nihstro includes nihstro: no warn * Chore: Enable warnings as errors on msvc + fix warnings fixes some more warnings clang-format * more fixes * Externals: Add target_compile_options `/W0` nihstro-headers and ... Revert "disable `C4715:not all control paths return a value` for nihstro includes" This reverts commit 606d79b55d3044b744fb835025b8eb0f4ea5b757. * src\citra\config.cpp: ReadSetting: simplify type casting * settings.cpp: Get*Name: remove superflous logs
