fix(Windows): Fix cast and control paths errors on windows

[TatianaKapos]

Summary:

Windows has a stricter set of rules for C++ files where we treat warning as error, the following files have fixes to correctly cast numbers and fix control path errors.

Control Path Error on React-Native-Windows repo:

1>react-native-windows\node_modules\react-native\ReactCommon\react\performance\timeline\PerformanceEntryReporter.h(138,1): warning C4715: 'facebook::react::PerformanceEntryReporter::getBufferRef': not all control paths return a value
1>react-native-windows\node_modules\react-native\ReactCommon\react\performance\timeline\PerformanceEntryReporter.h(154,1): warning C4715: 'facebook::react::PerformanceEntryReporter::getBuffer': not all control paths return a value

Apply these fixes will allow us to unfork these files in our repo :)

Changelog:

[GENERAL] [FIXED] - Fix cast and control paths errors on windows

Test Plan:

Tested on the RNW repo, these files are already forked with the respective fix
