* fix compilation issues for VS 16.8.* release
* - VS 16.8 changed its template instantiation model, so now the compiler checks the syntax used in template even when it's not instantiated. we were relying on that behavior to declare the list of required localized strings from a shared header => replacing that template with a macro.
* - fix 3 C++ `const auto&` bugs the new compiler was able to uncover
* - enabled /Zc:twoPhase- for bootstrapper and PowerToysSetupCustomActions to workaround 10.0.17134.0 headers' issue.
- PowerToysSetupCustomActions.vcxproj now uses 10.0.17134.0 instead of "latest" SDK
* - PowerToysSetupCustomActions project leverages `goto` operator's power extensively, and the new compiler was able to uncover new uninitialized variables behavior, restructured declarations and changed `NULL`s to `nullptr`s.
