Like the prior changes normalizing the inclusions within headers, this
tackles the cpp files of the RuntimeCommonB target, making these source
files consistent with their headers.
The strcasecmp and _stricmp functions expect the passed in strings to
be null-terminated, however we we're also exposing a std::string_view
overload for that function. std::string_view instances aren't required
to be null-terminated, so this makes the interface a little unsafe.
We can use std::lexicographical_compare() to provide the same behavior
and also properly handle the case of non-null-terminated strings.
