This component creates a GPT on a Block device. It supports the common actions, as in adding, deleting and modifying entries in the GPT, while considering alignment constraints. If needed it will round the length of a partition down to meet those constraints. The component will not perform layout checking, i.e., it does not care about overlapping partitions. Only when apping a partition it will make sure that the partition will fit. Please read _repos/gems/src/app/gpt_write/README_ for more detailed information on how to use the component and feel free to check out _repos/gems/run/gpt_write.run_. Fixes #2814.
