Subject: [PATCH] platforms/windows: fix deprecated C++ 20 implicit capture of
 this in [=]

With MinGW, GCC and Clang `[=, this]` is acceptable in C++20 mode, but
MSVC on the CI still builds with C++17. So use `[&]`, the other two
variables used inside the lambda are (const) built-in types, taking by
reference is the same as taking by copy.

Amends a90d99d8da9b2be2e6b8e981cd9dabfb1641e985.
