libcamera: ipa: Test control structure size with static_assert
The control-related structures ipa_controls_header,
ipa_control_value_entry and ipa_control_range_entry define the IPA
protocol and are thus part of the ABI. To avoid breaking it
inadvertently, use static_assert() to check the size of the structures.
