Deeptanshu Lal e4f89445b9 [Tools] Add synthetic shader dump tool for the Gen5 translator (#111) ...

SharpEmu.Tools.ShaderDump feeds hand-assembled Gen5 (gfx10) instruction
words — cross-checked against LLVM's AMDGPU target definitions — through
the real Gen5ShaderTranslator -> Gen5SpirvTranslator pipeline via
reflection (no emulator source changes; the project is not in the main
solution) and dumps the resulting vertex/compute SPIR-V blobs for
inspection with spirv-val / spirv-dis.

Each bundled program carries an expectation: fmac/muls/sopp-hints/exec
must decode and emit both stages, while sopp-mode (s_round_mode,
s_denorm_mode) pins the loud unknown-sopp decode failure those FP MODE
writes must keep producing until their semantics are modeled (#108). Any
unexpected outcome makes the tool exit non-zero, so it can gate scripts
or CI.

The exec program computes real ALU results and stores them with
buffer_store_dword, toggling EXEC off and on around a pair of stores; its
exec-cs.spv blob is designed for numeric verification on a real Vulkan
device (follow-up tool).

All dumped blobs pass spirv-val --target-env vulkan1.3.
