While cube face coordinates are nominally already in the [0.0, 1.0]
range due to the projection of the sampling coordinates onto the cube
face, the projection doesn't result in such normalized cube face
coordinates for Inf and NaN values in the sampling coordinates.

This change causes us to always clamp, matching the legacy OpenGL ES
code now.

With this change, we can now select implementations of most
transcendentals from either the "emulated" or "optimal"
namespaces. The emulated versions generally call the math.h
standard function on each component for vector types, while
the optimal versions typically implement some approximation
in Reactor to produce vectorized code.

Most of the optimal versions were taken directly from ShaderCore.cpp,
except for ASin, for which I implemented an 8-term approximation. The
new versions are faster, and pass all deqp precision tests.

Here's a table of benchmarks that show the performance improvements that
were made. Note that Asin and Acos now take a Precision parameter for
Full and Relaxed precision:

This is a major reworking of the way the debugger is implemented.

Instead of generating shader code that is continually driving `vk::dbg` state, the debugger now:
* Maintains a full shadow copy of all Intermediate values (SSA)
* Only calls out to C++ whenever a trap is set
* Only constructs and updates the `vk::dbg` state when a trap is hit

The main goal of this reworking is to properly support OpenCL.Debug.100's DebugValue instructions that may use deref expressions
(See https://www.khronos.org/registry/spir-v/specs/unified1/OpenCL.DebugInfo.100.html#_debug_operations_a_id_operation_a)
These are remarkably hard to implement without having everything backed with real memory.

The resulting reimplementation is:
* Much, much faster (>1000x faster for sample apps I've tried). Only ~2x slower than non-debug enabled SwiftShader now.
* Uses much less runtime memory.
* Much cleaner, removing a load of template magic for setting variable state that was extremely hard to follow
* More thoroughly commented, explaining each component and method.

While the memory layout for vec3 will be identical to a vec4, this allows us to specialize templates to distinguish between `vec3` and `vec4`.

This debug instruction partially updates a local variable with SSA values.

This is typically used to update a `DebugLocalVariable` of a composite type, which holds structure member offsets from a base address.
To handle these, we allocate shadow memory to hold a copy of the entire variable in contiguous memory and have the `DebugLocalVariable` point to this memory. Whenever we encounter a `DebugValue`, we copy the necessary fields to the
shadow memory.

This approach is simplier and more performant than attempting to fiddle with `vk::dbg::Value`s for each `DebugValue`.

Previously the way to create `VariableContainer`s was to call
`createVariableContainer()` on the `Context::Lock`. This was required so that debug-client requests to inspect the container's contents can be done with a simple map lookup.
Creating variable containers is a high frequency operation, and obtaining a `Context::Lock` (unsurprisingly) requires acquiring a mutex lock, which across multiple threads results in significant mutex lock contention.

To dramatically help with debugger performance, we can now construct `VariableContainer`s outside of the lock. This is achieved by registering the variable container in the context map only when it is handed to the client. This only occurs when there's a DAP transaction, which is orders of magnitude less frequent.

Constant arrays are allocated in the same 'register file' as the one
for per-program uniforms, to support dynamic indexing. While we had
a special case for that in OutputASM::registerType(), in registerIndex()
we were actually allocating them in the temporaries register file. This
led to assigning the same register index range twice, leading to
overwriting the per-program uniforms with constant array data in the
shader.

Unlike image views, buffer views don't have a component mapping field,
so we were setting the mapping to identity swizzles for uniform texel
buffers. However, we also use the component mapping for assigning 0 or 1
to components not provided by the texel format:

This change ensures we still get the 0 and 1 in the desired channels for
uniform texel buffers.

https://gitlab.khronos.org/vulkan/vulkan/-/merge_requests/3399 clarified
that when identity component swizzle is expected, one can also use the
corresponding component enum.
