libflashrom: Add API for capabilitible chips

There were no options available to obtain the list of
compatible chips for the programmer. The implementation is based
on flashrom_supported_flash_chips and flashrom_flash_probe.
Arrays of constant strings are returned, and the array must be
freed using flashrom_data_free.

Testing: Both unit tests and CLI tools serve as libflashrom clients.
    All unit tests run successfully.
    Tests are moved because there is a bug in spi test. It does
    not clean everything. WIP
