Update Steamworks SDK from v1.57 to v1.58a (#2363)

The next PR after #2350 and #2343. This PR contains the following changes: 1. Update SDK from v1.57 to v1.58a. 2. Improved the Shell Makefile (the part related to the Steamworks extension). - Moved building the fake API process inside a separate Makefile specific to the fake API. 3. Cleaned some comments including flushing the Steamworks Makefile. 4. Fixed the README.md file. 5. Improved documentation. 6. Created a separate Makefile for the fake Steamworks API. 7. Added v1.58a official headers. 8. Fixed .gitignore file. --------- Signed-off-by: Saif Kandil <74428638+k0T0z@users.noreply.github.com>
