[vulkan, android] Initial implementation of LSFG-VK (#4263)

Pretty much self explanatory, own implementation based on LSFG-VK available with some additional reverse engineer work for the actual use of shaders inside Lossless.dll, we don't store/ bundle any tools that bypass security and self ownership: to use this feature is required to own your own copy of Lossless Scaling and I encourage to support developers behind this work.

Special thanks:

1.- THS - Original developer behind Lossless Scaling
2.- PancakeTAS - Developer behind LSFG-VK
3.- The Big Smolio The Sleeper (@gidoly)
