* Ensure device lost closure is called exactly once before being dropped.
This requires a change to the Rust callback signature, which is now Fn
instead of FnOnce. When the Rust callback or the C closure are dropped,
they will panic if they haven't been called. `device_drop` is changed
to call the closure with a message of "Device dropped." A test is added.
* Remove some locks in BindGroup
These are only written to clear the vectors when triaging bindgroups for destruction, which is not necessary. We can let the reference counts drop when the bind group is dropped.
* Make the mem_leak test pass again
We allocate a String every time we want to get a label for logging. The string is also allocated when logging is disabled. Either way, the allocation is unnecessary. This commit replaces the String with a dyn Debug reference which does not need any allocation.
* Remove the abstractions in resource maps
ResourceMaps had a rather convoluted system for erasing types that isn't needed anywhere except in one place in the triage_resource function. Everywhere else we are always dealing with specific types so using a member of the resource maps is simpler than going through an abstraction. More importantly there was a constraint that all contents of the resource maps implement the Resource trait which got in the way of some of the ongoing buffer snatching changes.
This commit simplifies this by removing the abstraction. Each resource type has its hash map directly in ResourceMaps and it is easier to have different requirements and behaviors depending on the type of the each resource.

The general idea is to register postpone reigistering the buffer until towards the end of the function so that our unique reference to it lets us easily snatch the raw buffer if an error happens.
Without the suffix, `Expression::Literal(Literal::F32)` expressions
get written without any suffix on the number, meaning that they get
re-parsed as `AbstractFloat` values. In theory, this should always be
fine, but since we don't actually support abstract types yet in all
the places we should, having them appear in the output causes
validation problems.
See also: #4863, which did the same for `i32` literals.
Without the suffix, `Expression::Literal(Literal::I32)` expressions
get written without any suffix on the decimal number, meaning that
they get re-parsed as AbstractInt values. In theory, this should
always be fine, but since we don't actually support abstract types yet
in all the places we should, having them appear in the output causes
validation problems.
