Add support for serializing and deserializing control values that store
arrays of values. The serialized format is extended to explicitly handle
arrays.

Use the zero-copy variant of ByteStreamBuffer::read() to read packet
headers and control entries. This enhances the performance of
ControlList and ControlInfoMap deserialization.
Deserialization of the actual ControlValue is untouched for now and will
be optimized later.

Use the ControlValue::data() function to access raw data stored in the
control value and simplify serialization.

Replace the default case with an explicit ControlTypeNone case in
ControlSerializer::load() to catch omissions when adding new control
types.
A return statement needs to be added to the end of the function to avoid
gcc incorrectly reporting that some exit paths don't contain a return
statement. The compiler will still warn that not all cases are handled
when adding a new control type.

Add a data() function to the ControlValue class to expose the raw data
stored by the class as a Span<const uint8_t>. This will be useful to
simplify the serialization of ControlValue instances.
The size computation for the raw data is moved from the
ControlSerializer, which is updated accordingly to use the data()
function in order to access the size. Simplification of the
ControlSerializer will happen in a subsequent change.

The ControlSerializer::serial_ member variable isn't initialized. Add a

Add a new ControlSerializer helper to serialize and deserialize
ControlInfoMap and ControlList instances. This will be used to implement
the C IPA protocol and the communication with IPA through IPC.
