writer::spirv::Function attempted to append a trailing OpReturn if the
function does not end with a terminating instruction. This wasn't
considering functions that have a non-void return type.
This has now been moved to spirv::Builder::GenerateFunction(),
where we can actually examine the function return type, and generate a
zero-expression to return if we need to.
Note: this was masked by WGSL validation that required all functions to
end with a return statement.

The SwitchCaseBlockStatement was bound to the BlockStatement of an ast::CaseStatement, but we had nothing that mapped to the actual ast::CaseStatement.
sem::CaseStatement replaces sem::SwitchCaseBlockStatement, and has a Block() accessor, providing a superset of the old behavior.
With this, we can now easily validate the `fallthrough` rules directly, instead of scanning the switch case. This keeps the validation more tigtly coupled to the ast / sem nodes.

Change backend connection in Instance.cpp to store a bitset of
backends that have been connected. This lets us only connect to a
single backend if AdapterDiscoveryOptions are passed explicitly,
and track which connections have/have not been made. Later, we can
connect to the rest of the backends if more are requested.
This is part of some improvements to the existing code so we can
selectively discover adapters and control discovery of the
high-performance, low-power, and fallback WebGPU adapters.

All of these root constants are set when a bind group holding

using reflection data to only set constants that are needed

FXC sometimes miscompiles code when optimizing (/O2), and there is no
discernable workaround. This change sets the optimization level to /O0
when compiling shaders with FXC.
Also, no longer default to enabling EmitHLSLDebugSymbols in Debug
builds, which disabled optimizations (/Od). This confused me a few
times, and is not necessary since we can set this toggle via command
line.
