Major: Improve GEMM performance and add Level 3 BLAS/mixed-precision support

• Improve the performance of the existing GEMM implementation:
  • gemmul8::gemm, gemmul8::gemmLt
• Add support for the following Level 3 BLAS-like matrix operations:
  • SYMM (gemmul8::symm, gemmul8::symmLt)
  • SYRK (gemmul8::syrk, gemmul8::syrkLt)
  • SYR2K (gemmul8::syr2k, gemmul8::syr2kLt)
  • SYRKX (gemmul8::syrkx, gemmul8::syrkxLt)
  • HERK (gemmul8::herk, gemmul8::herkLt)
  • HER2K (gemmul8::her2k, gemmul8::her2kLt)
  • HERKX (gemmul8::herkx, gemmul8::herkxLt)
  • TRMM (gemmul8::trmm, gemmul8::trmmLt)
  • TRSM (gemmul8::trsm, gemmul8::trsmLt)
  • TRTRMM (gemmul8::trtrmm, gemmul8::trtrmmLt): triangular-by-triangular matrix multiplication
• Add support for mixed-precision execution
• Add workspace-query support by calling GEMMul8 routines with work == nullptr
• Extend gemmul8::workSize to support the routines listed above except TRSM
• Add gemmul8::workSizeTrsm for TRSM workspace-size calculation
• Add TRSM block-size control APIs for the internal blocked algorithm:
  • gemmul8::set_block_size_trsm(int nB)
  • gemmul8::get_block_size_trsm()
• Add overload (Hook Mode) support for the routines listed above
• Add overload (Hook Mode) support for _64, 3m, and 3m_64 variants where applicable
• Change the GEMMul8 routine argument type from unsigned num_moduli to int num_moduli
