Add Lua component (IEC-470)

[georgik]

The Lua component is getting popular, so idea is to move it under Espressif namespace.

Formerly it was hosted here: https://github.com/georgik/esp-idf-component-lua

Component Registry: https://components.espressif.com/components/georgik/lua/

All builds are green, just one is failing in picolib with from ESP-IDF, I guess this is not specific to this component:

warning: times is not implemented and will always fail

Any idea how to resolve it?

@suda-morris I'm trying to pass tests, yet still one is failing.
It seems that in the particular version there is issue with: times is not implemented and will always fail
Build and Run Apps / Build Apps (latest, 3) (pull_request)

Should I add into .ignore_build_warnings.txt:
warning: times is not implemented and will always fail

or is there any other recommended approach, since warning appears in the final linking stage of lua_example for ESP32 target. The warning originates from system library (picolibc), not Lua component code. The times() POSIX function isn't implemented in ESP32's libc but gets linked anyway.

@suda-morris @Lapshin All checks seems to be green. Who could confirm the merge?
