[lldb] Fix build break on windows (#84863)
This is a one line fix for a Windows specific (I believe) build break.
The build failure looks like this:
`D:\a\_work\1\s\lldb\source\Symbol\Symtab.cpp(128): error C2440:
'<function-style-cast>': cannot convert from 'lldb_private::ConstString'
to 'llvm::StringRef'

`
The StringRef constructor here is intended to take a ConstString object,
which I assume is implicitly converted to a std::string_view by
compilers other than Visual Studio's. To fix the VS build I made the
StringRef initialization more explicit, as you can see in the diff.
