Adding recipes for common OHOS headers and libraries:
- syspara-lite-framework - System Parameter library
- syspara-lite-hals-headers - System Parameter HAL header files
- syspara-lite-headers - System Parameter header files
- utils-native-lite - Generic OHOS header files

Recipe naming resembles original OHOS repository names
with the exception when the repository contains only
single library source code - in such case recipe name is the
same as the library name it provides
