Update the README for 1.5.

[hrydgard]

As always, I probably forgot something important?

Worth calling out sustained performance mode (#9901), adhoc server (#9984), Linux controller mappings (#9997)?

Should we add " * Assorted minor compatibility fixes, code cleanup and performance improvements" like 1.4.0 had? It's true this time around too.

[hrydgard]

Yeah, bit busy but I'll try to get it out tomorrow or the day after.

I know 1.5 introduced Vulkan feature parity with other renderers like buffered rendering, stencil support, etc..

Is this meant to be understood through the fact Vulkan support is now enabled in Android? Because I don't think it's part of multithreading Vulkan.

Personally, but I could be wrong, the fact it's feature-parity is nearly (if not completely) the same as the other renderers is something of note? Or am I literally blind and reading over it without realizing?

Kind regards,

It is of note mainly because 1.4 had basic but very far from feature-complete Vulkan support on Windows only.

[DJScias]

Well, I figured it was of note. Just didn't see it in the PR readme change written down unless I missed it. :)

Kind regards,
