ASoC: cs-amp-lib-test: Add test cases for cs_amp_set_efi_calibration_data()

Add a set of test cases for cs_amp_set_efi_calibration_data().

Broadly there are two type of behavior being tested:

How the EFI is updated:
- Create a new EFI
- Overwrite part of existing content
- Overwrite part of zero-filled preallocated content
- Grow the file to append new content

And how the location within the content is chosen:
- Overwrite a specific array entry
- Overwrite an entry with the same calTarget (silicon ID)
- Overwrite a free entry
- Append after existing data

Plus some cases for error conditions.
