py/modsys: Add sys.implementation._build entry.
For a given MicroPython firmware/executable it can be sometimes important
to know how it was built, which variant/board configuration it came from.
This commit adds a new field `sys.implementation._build` that can help
identify the configuration that MicroPython was built with.
For now it's either:
* <VARIANT> for unix, webassembly and windows ports
* <BOARD>-<VARIANT> for microcontroller ports (the variant is optional)
In the future additional elements may be added to this string, separated by
a hyphen.
Resolves issue #16498.
