Move to ASF4 and introduce SAMD51 support. (#258) * atmel-samd: Remove ASF3. This will break builds. * atmel-samd: Add ASF4 for the SAMD21 and SAMD51. * Introduce the supervisor concept to facilitate porting. The supervisor is the code which runs individual MicroPython VMs. By splitting it out we make it more consistent and easier to find. This also adds very basic SAMD21 and SAMD51 support using the supervisor. Only the REPL currently works. This begins the work for #178.

/*
Correct _etext location; clean up .ld files 1. Make _extext and _sidata coincide. Old _etext location did not include .ARM.exidx sections, which were usually absent but not always. So flash data was copied to RAM in wrong place. 2. Use decimal constants with "K" and "M" suffixes in .ld files instead of hex constants, to make them easier to read and check for accuracy.
