Now that we can actually use std::optional on macOS, we don't need to
continue using boost::optional here.

tr() will not function properly on static/global data like this, as the
object is only ever constructed once, so the strings won't translate if
the language is changed without restarting the program, which is
undesirable. Instead we can just turn the map into a plain old function
that maps the values to their equivalent strings. This is also lessens
the memory allocated, since it's only allocating memory for the strings
themselves, and not an encompassing map as well.

qt: Add UI to manage emulated user profiles

Prevents bug where old username would remain if the new username was shorter in length.

We can just use the facilities that Qt provides instead of pulling in
stuff from common. While we're at it, we can also simplify the nearby
logging statement's argument by just calling .toStdString()

These are user-facing strings, so they should be marked as translatable

This gets rid of an unnecessary type conversion. We can just use the
regular QStringLiteral to already format the string as the type
setWindowTitle accepts instead of converting from a std::string
instance.

This is only stored to, but never read from.

This also gets rid of variable shadowing related to the lambda parameter
a little bit below this code as well.

This hasn't been used since ba8ff096

Same behavior, less code.

We can just call the function instead of duplicating the code here. This
also prevents an unused function warning.

We also don't need to take the lambda capture by reference. It's just a
u64 value, so by value is fine here.

Also gets rid of an unused variable.

Just a few overlooked services.

Makes the class layout consistent with the others.

Added break types to svcBreak
