COMPMID-3578: Update FP32/int8 kernel selection. Upgrade the current 'is_preferred()' mechanism with a new framework, where kernels instead provide an estimated cycle count figure. Compatibility with old mechanism is achieved via a wrapper which replaces a "true" result with an estimate of 0, and a "false" result with UINT64_MAX. This mechanism is then used to select between 'interleaved' and 'hybrid' FP32 NEON kernels. This uses a simple system based on counting MACs performed and bytes of data transferred (for rearrange/merge operations) and dividing by fixed performance figures, which are provided for A53, A55, A73 and 'default' figures (based on A76). Separately, a new route for performing int8 GEMMs by using the int16 kernel is provided. This performs significantly (for uint8) or slightly (for int8) better on A53 than the existing int8 route. Optimized 8-to-16 bit transforms are also included.
