* 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.

This proves a flag in msl::PipelineOptions that attempts to write all
Metal vertex entry points to use a vertex pulling technique. It does
this by:
1) Forcing the _buffer_sizes structure to be generated for all vertex
entry points. The structure has additional buffer_size members that
contain the byte sizes of the vertex buffers.
2) Adding new args to vertex entry points for the vertex id and/or
the instance id and for the bound buffers. If there is an existing
@builtin(vertex_index) or @builtin(instance_index) param, then no
duplicate arg is created.
3) Adding code at the beginning of the function for vertex entry points
to compare the vertex id or instance id against the lengths of all the
bound buffers, and force an early-exit if the bounds are violated.
4) Extracting the raw bytes from the vertex buffer(s) and unpacking
those bytes into the bound attributes with the expected types.
5) Replacing the varyings input and instead using the unpacked
attributes to fill any structs-as-args that are rebuilt in the entry
point.
A new naga test is added which exercises this flag and demonstrates the
effect of the transform. The msl generated by this test passes
validation.
Eventually this transformation will be the default, always-on behavior
for Metal pipelines, though the flag may remain so that naga
translation tests can be run with and without the tranformation.
Replace the `wgpu_core:🆔:Id::transmute` method, the `transmute`
private module, and the `Transmute` sealed trait with some associated
functions with obvious names.

* Added tests for texture zero init
sadly, they are typically passing even if texture zero init isn't doing its job
However, they form nice isolated examples for testing out texture initialization
It could be possible to dirty texture memory prior to ensure zero init did the job
* texture init tracker
* tracking texture init requirements for bind group, transfer and rendertarget
* texture clears for texture init
* queue submit
* write_texture
* Enforce presence of either render target or copy_dst flag
* clear render targets also with using buffer copies
enforce COPY_DST usage now on all textures
* adjust ImageSubresourceRange.layer_range calculation for 3D textures
init_tracker has now a `discard` function to get single data points back to uninitialized
use new standardized partition_point function
* track init state for discarded textures from renderpasses
missing:
* init on the fly if discarded is found within command buffer
* handle discarding only stencil or only depth
* added tests for zero init after discard
* tracking discarded surfaces now in separate struct, piping all inits through utility function
allows to resolve discard/init_action interactions
* Move various memory init code to separate mod
CommandBufferTextureMemoryActions is now fully encapsulated
* implemented discard init fixups for everything but renderpass
* render passes also cause now discard fixups
* fixup_discarded_surfaces takes now an iterator instead of Drain
* Add memory init test for discarding depth targets
* handle divergently discarded depth/stencil target
* comment & clippy fixes
* fix collect_zero_buffer_copies_for_clear_texture yielding block breaking copies
* [pr feedback] minor cleanup in zero_init_texture_after_discard, `use` hygenie
* [pr feedback] fix bug in ImageSubresourceRange range utils
* [pr feedback] fix texture tracker check, bundle transition_texture on init, cleanups
* Implemented drop for InitTrackerDrain
* remove incorrect comment about extents in add_pass_texture_init_actions
* Fix unit test & clippy issues in init_tracker
* enable CLEAR_COMMANDS feature for all adapters
* replaced fill_buffer with clear_buffer (minus variable value)
* Improve clear buffer/texture test
and remove unused clear-buffer.ron test
* renamed clear_image to clear_texture
* skeleton for new wgpu-hal clear_texture
* clear_texture implementation for vulkan
* clear_texture now restricts usage
* clear_texture implementation for dx12
* Implemented clear_texture for Metal backend
* Clean up GLES clear_buffer and leave note on how to implement clear_texture in the future
* fix linux compilation & formatting issues
* comment & namespace fixes
* Extent3d has now a simple mipmap calculating function
Fix incorrect use of texture.size in clear_texture for metal/dx12
Fix incorrect mip/layer ranges in clear_texture for metal/dx12
