build: Add meson build
Changes to note,
- `with_systemdsystemunitdir` and `with_tmpfilesdir` is removed since it
is not being documented nor used in OpenBMC.
- Removed the Code coverage feature with `-DDHAVE_GCOV`, since it is not
used and meson covers it.
- Removed `--enable-oe-sdk` for using the OpenBMC SDK. It should work
directly with no change required.
Tested:
```
