Move the functionality for the following components to the new
base support library:
- BoundMethod
- EventDispatcher
- EventDispatcherPoll
- Log
- Message
- Object
- Signal
- Semaphore
- Thread
- Timer
While it would be preferable to see these split to move one component
per commit, these components are all interdependent upon each other,
which leaves us with one big change performing the move for all of them.

Use the newly introduced function to retrieve the size of
the JPEG encoding destination buffer, in order to calculate where
the JPEG_BLOB_ID should be placed.

Use the newly introduced CameraBuffer class as the type for the
destination buffer in the PostProcessor class hierarchy in place of the
libcamera::MappedFrameBuffer one and use its API to retrieve the length
and the location of the CameraBuffer plane allocated for JPEG
post-processing.
Remove all the assumption on the underlying memory storage and only go
through the CameraBuffer API when dealing with memory buffers. To do so
rework the Encoder interface to use a raw pointer and an explicit size
to remove access to the Span<uint8_t> maps that serve as memory storage
for the current implementation but might not be ideal for other memory
backend.
Now that the whole PostProcessor hierarchy has been converted to use
the CameraBuffer API remove libcamera::MappedBuffer as base class
of the CameraBuffer interface and only reply on its interface.

The type of the destination buffer in PostProcessor::process() is
libcamera::Span. libcamera::Span is used for one dimension buffer
(e.g. blob buffer). The destination can be multiple dimensions
buffer (e.g. yuv frame). Therefore, this changes the type of the
destination buffer to MappedFrameBuffer.

The ExposureTime libcamera control is in microseconds while android and
our exif component use nanoseconds. Convert it appropriately.
CTS also expects the ExposureTime exif tag to match the ExposureTime set
in the android result metadata. Fix it.

Configure the thumbnailer based on the thumbnail parameters given by the
android request metadata. Only the thumbnail encoder needs to be
configured, and since it is only used at post-processing time, move the
configuration out of the post-processor constructor and into the
processing step.
Also set the following android result metadata tags:
- ANDROID_JPEG_THUMBNAIL_SIZE
- ANDROID_JPEG_THUMBNAIL_QUALITY

In Encoder::encode(), the |source| argument doesn't have to be a
pointer. This replaces its type, const pointer, with const
reference as the latter is preferred to the former.
libcamera::Span is cheap to construct/copy/move. We should deal
with the type as pass-by-value parameter. Therefore this also
drops the const reference in the |destination| argument.
