* Expose gpu allocation configuration options
This commit adds hints to control memory allocations strategies to the configuration options. These hints allow for automatic profiles such as optimizing for performance (the default, makes sense for a game), optimizing for memory usage (typically more useful for a web browser or UI library) and specifying settings manually.
The details of gpu allocation are still in flux. The goal is to switch vulkan and metal to gpu_allocator which is currently used with d3d12. gpu_allocator will also likely receive more configuration options, in particular the ability to start with smaller memory block sizes and progressively grow the block size. So the manual settings already provision for this upcoming option. Another approach could be to wait and add the manual option after the dust settles.
The reason for providing presets and defining values in the backends is that I am convinced that optimal fonigurations should take hardware capabilities into consideration. It's a deep rabbithole, though, so that will be an exercise for later.

* Ensure webgl example build only contains webgl and webgpu example build only contains webgpu
* fix ip printed on run-wasm
* Update examples on running examples on the web
These are being deprecated in the future in favor of the associated
constants (which are already being used in some code here), so this
consistently uses the preferred forms.
* Fix output args for render_to_texture example
* Fix output args for storage_texture example
* Fix dashes to underscore in example names.

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
* Downgrade resource lifetime management log level to trace.
Allow promoting it back to info via an feature flag.
* Don't filter out info and warning log in the examples.
* Changelog entry.
