fix(windows): skip hybrid GPU hook on single-GPU systems

[SeMmyT]

Summary

• Skip the NtGdiDdDDIGetCachedHybridQueryValue MinHook on single-GPU systems where it's unnecessary
• Prevents a crash loop (0xc0000005 in dxgi.dll) on Windows 11 24H2 build 29558+
• Adds proper error handling for MinHook API return values

Problem

The hybrid GPU workaround hook introduced in #3530 causes an access violation in dxgi.dll on recent Windows 11 builds (24H2, build 29558+) with single-GPU systems. The crash is deterministic — always at offset 0x6cb2f in dxgi.dll — and creates an infinite crash loop where the service wrapper restarts sunshine.exe every ~6 seconds.

Crash signature:

Faulting module: dxgi.dll (10.0.29558.1000)
Exception: 0xc0000005 (ACCESS_VIOLATION)
Offset: 0x000000000006cb2f

Root cause: the hook spoofs D3DKMT_GPU_PREFERENCE_STATE_UNSPECIFIED as the return value, but the updated dxgi.dll in build 29558 doesn't handle this state correctly on a code path that only executes when the hook is active.

Fix

Before installing the hook, enumerate DXGI adapters to detect if the system has multiple physical GPUs:

• Multi-GPU: install the hook as before (needed to prevent output reparenting)
• Single-GPU: skip the hook entirely (no reparenting issue exists)

Adapters are deduplicated by VendorId + DeviceId since the same physical GPU can appear as multiple DXGI adapters.

Also adds:

• Error handling for MH_Initialize() and MH_CreateHookApi() return values
• Logging for hook installation status (success, skip, or failure)

Test Plan

• Verified on RTX 4070 Ti single-GPU, Windows 11 24H2 build 29558, NVIDIA 591.86
• Should be tested on multi-GPU/hybrid systems to ensure hook is still applied
