Description
Vector DSP operations in Q15/Q31 fixed point, for targets without a hardware FPU (Cortex-M0, AVR). numx already has Q15/Q31/Q63 typedefs (numx_types.h) and a Q15 FFT (numx_fft_q15), this extends the same fixed-point approach to basic vector ops (dot, norm, add, scale) so those targets aren't limited to just FFT.

Research direction
Start by reviewing the Q15/Q31/Q63 typedefs in numx_types.h and the existing numx_fft_q15 implementation to understand the fixed-point conventions. Add coverage for Q15/Q31 dot, norm, add, and scale operations, with completion shown by tests that work without hardware floating-point support on the named target classes.
