Mostly workaround for vkAcquireNextImageKHR errors,
Create more cmdbuffers with slow vulkan implementation could produce
issues when old cmdbuffer is not finished but need to resize dynamic buffer.
Based on
```
Added additional image ready semaphore - this addresses validation errors
when calling vkAcquireNextImageKHR() which started appearing in SDK 1.3.275

* Build ref_gles1 only on Linux, it's of limited use under MacOS and Win.
* Fetch openal-soft from Github, the other mirror had several connection
problems in the past.
* Always include the latest curl.dll in Windows builds. Since this isn't
a stripped down build of curl, it's better to have it up to date.
* Make sure that we are on Ubuntu 22.04. Otherwise the binaries wouldn't
work on newer distros when `ubuntu-latest` becomes Ubuntu 24.04.
* Fix some typos.
Workaround for:
Validation Error: [ VUID-vkAcquireNextImageKHR-semaphore-01779 ] Object 0: handle = 0x90000000009, name = Semaphore: image available #0, type = VK_OBJECT_TYPE_SEMAPHORE; | MessageID = 0x5717e75b | vkAcquireNextImageKHR(): Semaphore must not have any pending operations. The Vulkan spec states: If semaphore is not VK_NULL_HANDLE it must not have any uncompleted signal or wait operations pending (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkAcquireNextImageKHR-semaphore-01779) (validation)
Using a more modern opengl code to make this part a little more efficient on modern cards to bind the buffers. We are simply binding and unbinding the buffer when it is full, on modern cards this is fine and perfectly efficient enough, same goes for CPU's.

* Mention some more new features added in the last years.
* Make clear that only FreeBSD, Linux and Windows have official support.
Everything else is community supported.
* Link to the official addons and yquake2remaster.
* Give some hints to bug reporters and contributors.
* Link to CI builds.
* Avoid relative links so that personal forks link back to the main
projects. If forks want to link to their own ressources, they can
edit the file.
Testbuild is applied to macos, linux, win32, win64.
Win32/64 additionally create release for tags.
Linux build is checked with disabled ffmpeg flag as LTS linux image
has unsupported ffmpeg version.
