Join all threads before returning from the test case, to ensure that
we don't return from `main` until all open `Device`s have been
dropped.
This avoids a race condition in glibc in which a thread calling
`dlclose` can unmap a shared library's code even while the main thread
is still running its finalization functions. (See #5084 for details.)
Joining all threads before returning from the test ensures that the
Vulkan loader has finished `dlclose`-ing the Vulkan validation layer
shared library before `main` returns.
Remove `skip` for this test on GL/llvmpipe. With this change, that has
not been observed to crash. Without it, the test crashes within ten
runs or so.
Fixes#5084.
Fixed#4285.

* hello_compute: check for missing command-line args
Fixes off-by-one error when checking for missing arguments.
Before this, running the example gave this scary looking error message:
```
$ cargo run --bin wgpu-examples hello_compute
Finished dev [unoptimized + debuginfo] target(s) in 0.13s
Running `target/debug/wgpu-examples hello_compute`
[2023-12-27T22:14:26Z ERROR wgpu::backend::direct] Handling wgpu errors as fatal by default
thread 'main' panicked at 'wgpu error: Validation Error
Caused by:
In Device::create_bind_group
Buffer binding size 0 is less than minimum 4
note: buffer = `Storage Buffer`
', wgpu/src/backend/direct.rs:3139:5
```
As this was the first example I tried to run, it almost scared me
away, thinking it was a driver issue.
Instead, without arguments the example should use defaults.
* Add PR #4939 to changelog as instructed
* Fix indentation in main examples readme file
* Update examples readme files
* Update hello_compute example readme and fix example not running with new command
* Fix srgb_blend example not working correctly and set readme accordingly
