This commit lets board use a different floating point mode rather than the usual soft-float that was the original default for all QEMU-based boards. The configuration options are the same available in the "stm32" port. Boards can set "MICROPY_FLOAT_IMPL" to either "float", "double", or "none" to indicate which floating point mode they want, and optionally "SUPPORTS_HARDWARE_FP_SINGLE" or "SUPPORTS_HARDWARE_FP_DOUBLE" can be set to 1 to further indicate the hardware capabilities of the hardware floating point unit, if present.
