Feature #27286: Add ColoredHashTSDFVolume support in rgbd module(CPU)

[huiyu-mcse]

Introduced 'ColoredHashTSDFVolume', a new CPU-only volume type extending 'HashTSDFVolume' with color integration support. This feature enables reconstruction of colored 3D scenes using aligned depth and RGB images, while benefiting from the memory and performance advantages of hashed volumetric fusion.

Main contributions:

• New data structure to store both TSDF and RGB color information
• Extended raycasting and fetch functions to support color output

This enhancement follows the direction proposed in issue #25155 and addresses feature request #27286.
