`DebugScope` was capturing a `string_view` in a lambda which is only
valid during the scope of this ctor. When the lambda gets invoked at a
later time, it will read undefined garbage. The lambda needs to make a
deep copy of this `string_view` into a `string` so that it is valid by
the time the scheduler invokes this lambda.
* shader_jit/tests: Add support for multiple inputs
Allows for multiple `Vec4f` inputs for each run
* shader_jit/tests: Add additional shader-jit tests
Add some more expansive tests for each of the shader-instructions for
regression-testing. `MAD`/`MADI` is not added due to an upstream bug in
nihstro:

Xbyak has a complete utility-class for determining the host-processor's
ISA-features such as SSE4.1, AVX, AVX2, AVX512{F,VL,DQ,VBMI,etc}, and so
on for further potential optimizations.
Was getting an unhandled `invalid_argument` [exception](https://en.cppreference.com/w/cpp/thread/thread/join) during
shutdown on my linux machine. This removes the need for a `StopBackendThread` function entirely since `jthread`
[automatically handles both checking if the thread is joinable and stopping the token before attempting to join](https://en.cppreference.com/w/cpp/thread/jthread/~jthread) in the case that `StartBackendThread` was never called.
