Add "(legacy)" for multi-install? Same below.

Done.

Looks like:
- GetBinariesClientStateKeyPath()
- GetBinariesClientStateMediumKeyPath()
- kBinariesPathName
become dead code after this CL? So maybe delete in this CL, or add TODO?

Good catch. I left these in because I think I'll have uses for them in
install_util and setup once those components use install_static (which is on
hold until these multi-install CLs land).

 std::wstring GetClientStateMediumKeyPath(const wchar_t* app_guid);
 std::wstring GetBinariesClientStateMediumKeyPath();
