Does this mean ESP32 micro-controlers will be supported ?

It does. Finally! Before you needed a special branch for your custom rustc esp32 builds. Now it should be a lot easier.

Nice to finally see mainline support. Though a bit of a day late and dollar short, considering expressif seems to be in the process of transitioning to RISC-V.

The title is very clickbaity and quite misleading. Part of the work has landed. It's still a ways away from being usable and being able to build any code.

It's a pity my XTensa in AMD Kaveri is never used...

Are there cheap RISC-V boards with WIFI, like ESP boards?

Well, the obvious answer would be the ESP32-C* series.
