* Windows: never load a dxcompiler.dll found on PATH; FXC unless DXC ships beside the app (#6756)

wgpu's Dx12Compiler::Auto loads dxcompiler.dll by name, so Windows takes the
first one on PATH. SolidCraft ships none, and DXC 1.8.2505 from other programs'
folders (Obsidian, NVIDIA SDK Manager) crashed every start with
EXCEPTION_ILLEGAL_INSTRUCTION during the viewport shader compile.

solidcraft_gpu::dx12_compiler() now chooses: WGPU_DX12_COMPILER as wgpu reads
it when it names a compiler; otherwise DXC from the dxcompiler.dll beside the
program, by its full path, else FXC. The window, the headless/CLI instance and
the test helpers start with it, and dx12_compiles_with_fxc follows it.
WGPU_DX12_COMPILER=dxc keeps the old lookup.

Fixes #6756
