chromeos-bootimage: Move building to a separate function

In preparation for supporting unified builds, which requires building for
multiple models, move the building code into a separate function.

Add some comments about the inputs and outputs for this function.

chromeos-bootimage: Compress assets before building

With unified builds we plan to build multiple images, one for each model.
Since they all use the same assets, we only need to compress them once.
So adjust the code to compress the assets before calling build_images().

Print a message while doing it since it takes a while.

chromeos-bootimage: Refactor build_image() to use an image type

Rather than passing in the whole filename to build_image(), pass just the
image type, as appended to the filename. So for "image.dev.bin" we pass
"dev" and for "image.bin" we pass "". This will allow unified builds to
provide a model suffix (in a future CL).

Also add some comments to the function.

chromeos-bootimage: Tighten the file installation wildcard

The current rule is "*image*.bin" which is confusing in that it suggests
that files are installed which do not start with "image". In fact this is
not true.

Adjust the install rule to "image*bin" to clarify this.

chromeos-bootimage: Support a directory and suffix for images

With unified builds we want to put images for a model in their own
directory and name them by model. Add two variables to permit this. At
present they are empty, but a future CL will make use of it. It is split
out here to aid review.

chromeos-bootimage: Support unified build

When unified build is enabled, build images for all models.

I'm not sure that we need a separate subdirectory for each model. I am
considering dropping that, depending on what happens with firmware update
(which I have not done yet).

chromeos-bootimage: Drop the build_image() public_name

There is not really any need for this. We can just print the output
filename which is descriptive enough.

Drop this parameter and make the image_type first, so it is easier to see
what each build_image() call does.
