Add license header to (almost) all files. Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Refine iMX RT memory layout and add three boards Introduces a way to place CircuitPython code and data into tightly coupled memory (TCM) which is accessible by the CPU in a single cycle. It also frees up room in the corresponding cache for intermittent data. Loading from external flash is slow! The data cache is also now enabled. Adds support for the iMX RT 1021 chip. Adds three new boards: * iMX RT 1020 EVK * iMX RT 1060 EVK * Teensy 4.0 Related to #2492, #2472 and #2477. Fixes #2475.

Before this patch such a call would allocate a super object on the heap and then load the foo method and call it right away. The super object is only needed to perform the lookup of the method and not needed after that. This patch makes an optimisation to allocate the super object on the C stack and discard it right after use.

py: Combine 3 comprehension opcodes (list/dict/set) into 1. With the previous patch combining 3 emit functions into 1, it now makes sense to also combine the corresponding VM opcodes, which is what this patch does. This eliminates 2 opcodes which simplifies the VM and reduces code size, in bytes: bare-arm:44, minimal:64, unix(NDEBUG,x86-64):272, stmhal:92, esp8266:200. Profiling (with a simple script that creates many list/dict/set comprehensions) shows no measurable change in performance.

py: Compress load-int, load-fast, store-fast, unop, binop bytecodes. There is a lot potential in compress bytecodes and make more use of the coding space. This patch introduces "multi" bytecodes which have their argument included in the bytecode (by addition). UNARY_OP and BINARY_OP now no longer take a 1 byte argument for the opcode. Rather, the opcode is included in the first byte itself. LOAD_FAST_[0,1,2] and STORE_FAST_[0,1,2] are removed in favour of their multi versions, which can take an argument between 0 and 15 inclusive. The majority of LOAD_FAST/STORE_FAST codes fit in this range and so this saves a byte for each of these. LOAD_CONST_SMALL_INT_MULTI is used to load small ints between -16 and 47 inclusive. Such ints are quite common and now only need 1 byte to store, and now have much faster decoding. In all this patch saves about 2% RAM for typically bytecode (1.8% on 64-bit test, 2.5% on pyboard test). It also reduces the binary size (because bytecodes are simplified) and doesn't harm performance.
