Platform dependent non-cryptographically secure random number support.

If the entropy support of the platform has sufficient performance to support random request then select that. Otherwise, select the XOROSHIRO algorithm

Direct dependencies¶

(SOC_MKW40Z4 && SOC_SERIES_KINETIS_KWX) || (SOC_MKW41Z4 && SOC_SERIES_KINETIS_KWX) || ENTROPY_GENERATOR || ENTROPY_HAS_DRIVER || TEST_RANDOM_GENERATOR

(Includes any dependencies from ifs and menus.)
