Port yuzu-emu/yuzu#2457: "yuzu/{about_dialog, main}: Specify string conversions explicitly for SCM-related info" (#4774)

* yuzu/about_dialog: Specify string conversions explicitly

Specifies the conversions explicitly to avoid implicit conversions from
const char* to QString. This makes it easier to disable implicit QString
conversions in the future.

In this case, the implicit conversion was technically wrong as well. The
implicit conversion treats the input strings as ASCII characters. This
would result in an incorrect conversion being performed in the rare case
a branch name was created with a non-ASCII Unicode character, likely
resulting in junk being displayed.

* yuzu/main: Move window title updating logic to its own function

For similar reasons to the previous change, we move this to a single
function, so we don't need to duplicate the conversion logic in several
places within main.cpp.
