Subject: [PATCH] Replace implicit lamda captures for C++20

Implicit capture of 'this' with a capture default of '=' is deprecated
in C++20. While the standard recommends replacing '=' with '=, this',
that syntax is not C++17 compatible, and we will likely need some
transition period where obs-studio and its modules are still built
using C++17.
