Consolidate Vive SDK lib + DLLs under ThirdParty/VBS_SDK/Win64/

Why: vendor SDKs distributed inside UE plugins typically ship a single
folder per platform rather than the Unix-style include/lib/bin split.
Grouping VS_PC_SDK.lib alongside the three runtime DLLs matches what
HTC and most XR SDKs publish and keeps the layout closer to what a
maintainer expects when dropping in a new SDK release.

- Move VS_PC_SDK.lib from lib/Win64/ into Win64/ alongside the DLLs.
- Remove the now-empty lib/ and bin/ subdirectories.
- Update Build.cs to use a single Win64Dir variable.
- Update FilterPlugin.ini to reference the consolidated path.

Validated by clean rebuilds of PS_ViveVBSEditor and PS_ViveVBS Win64
Development targets, both exit 0 with the three DLLs auto-copied next
to the binary.
