Léo Lam fb124c2eb0 Use nested namespaces for IOS HLE 
Pretty much all of the source files contain the following:

    namespace IOS
    {
    namespace HLE
    {
    namespace <name>
    {
    // actual code here
    }  // namespace <name>
    }  // namespace HLE
    }  // namespace IOS

which is really verbose boilerplate, because most of the files inside
of Core/IOS are for IOS HLE.

This commit replaces that with a more concise `namespace IOS::HLE`
or `namespace IOS::HLE::(name)`.
