📄 Description

This patch adds cpu backend support and fix build failures on POWER systems

  1. Added ggml-cpu/arch/powerpc directory to host Power-specific code.
  2. Fixed compilation errors in sgemm.cpp and simd-mappings.h where vector was not defined by explicitly mapping it to __vector.
  3. Resolved build errors from -mcpu=power11 by replacing it with the supported -mcpu=power10.
