Arm CortexM lowbit export toolchain definition and integration in aidge

First steps

• Generate configuration files for STM32-F746ZG & STM32-H743ZI
• Run lowbit MAC kernel on F7 & H7 :
  • Mac 8W/8A
  • Mac 4W/8A
  • Mac 4W/4A
  • Mac 1W/8A
  • Mac 1W/7A
  • Mac 1W/5A
  • Mac 1W/4A
• Runtime benchmark for convolution in each precision configuration
• Test conv2D with Weights Interleaving

Note: I just saw this comment in the saturate method https://gitlab.eclipse.org/eclipse/aidge/aidge_export_arm_cortexm/-/blob/dev/aidge_export_arm_cortexm/_N2D2/static/utils.hpp?ref_type=heads#L145-151

    // In N2D2 Export, saturate wants the number of bits to store the outputs
    // It was given as a global variable "NB_BITS"
    // Old code
    // return saturate<Output_T>(rescaling(weightedSum, output), NB_BITS);
    // For the current purposes, we adapt the nbbits depending the output datatype
    // Change it for future work in it is required
