pipeline: rpi: Fix invalid access to CameraData::sensorInfo_

sensorInfo_ currently gets populated in configureIPA(), but is possibly
referenced in platformConfigure() which is called first. Fix this by
populating sensorInfo_ straight after configuring the sensor in
configure(), ensuring the fields are valid in the call to
platformConfigure().

ipa: rpi: pisp: Add '-Wno-address-of-packed-member' to the compiler args

This is needed for when we start using the UAPI kernel headers which
use "__attribute__((packed))" to force structure packing as required by
the kernel. The compiler complains about taking a possibly unaligned
address of a packed structure even though the structure has been hand
packed.

Alpha release

libcamera v0.3.0

abi-compliance checker reports 99.7% binary compatibility and 99.9% source
compatibility between v0.2.0 and v0.3.0. The SONAME has been updated
accordingly and applications must be relinked against this version of
libcamera.

 Total binary compatibility problems: 2, warnings: 0
 Total source compatibility problems: 2, warnings: 0

Specifically, the symbol
  - ControlList::merge(struct ControlList const& source )
 has been replaced with the new symbol:
  - ControlList::merge ( struct ControlList const& source, enum ControlList::MergePolicy policy )
