tests/import: Add test for importing x64 native code.

py: Rework and compress second part of bytecode prelude. This patch compresses the second part of the bytecode prelude which contains the source file name, function name, source-line-number mapping and cell closure information. This part of the prelude now begins with a single varible length unsigned integer which encodes 2 numbers, being the byte-size of the following 2 sections in the header: the "source info section" and the "closure section". After decoding this variable unsigned integer it's possible to skip over one or both of these sections very easily. This scheme saves about 2 bytes for most functions compared to the original format: one in the case that there are no closure cells, and one because padding was eliminated.

py/persistentcode: Make .mpy more compact with qstr directly in prelude. Instead of encoding 4 zero bytes as placeholders for the simple_name and source_file qstrs, and storing the qstrs after the bytecode, store the qstrs at the location of these 4 bytes. This saves 4 bytes per bytecode function stored in a .mpy file (for example lcd160cr.mpy drops by 232 bytes, 4x 58 functions). And resulting code size is slightly reduced on ports that use this feature.
