This test:
(1) signs a font file with the test key.
(2) side-loads the test cert to the device under test.
(3) verifies that the signed font file can be installed.

The device must be rootable for doing step (2).

As general background, OWNERS files expedite code reviews by helping
code authors quickly find relevant reviewers, and they also ensure
that stakeholders are involved in code changes in their areas.

Some teams under frameworks/base/ have been using OWNERS files
successfully for many years, and we're ready to expand them to cover
more areas.  Here's the historical coverage statistics for the last
two years of changes before these new OWNERS changes land:

-- 56% of changes are fully covered by OWNERS
-- 17% of changes are partially covered by OWNERS
-- 25% of changes have no OWNERS coverage

Working closely with team leads, we've now identified clear OWNERS on
a per-package basis, and we're using "include" directives whenever
possible to to simplify future maintenance.  With this extensive
effort, we've now improved our coverage as follows:

-- 98% of changes are fully covered by OWNERS
-- 1% of changes are partially covered by OWNERS
-- 1% of changes have no OWNERS coverage

This specific change is automatically generated by a script that
identifies relevant "include" directives.

Previously, we used PRODUCT_COPY_FILES. However, that does not allow
overriding the file to use a different one on a per-device basis.
This change migrates the logic to using a BUILD_PREBUILT module
called fonts.xml.
To add additional fonts, the add_additional_fonts.py script has been
added. If ADDITIONAL_FONTS_FILE is defined, add_additional_fonts.py
is run and generates a new version of fonts.xml that contains the
content of ADDITIONAL_FONTS_FILE added where
"<!-- fallback fonts -->" is added.

Update fonts.xml to use NotoSansKhmer-VF.ttf.

The weight range of Khmer is also extended to have 9 weight instances
(three more than Roboto with 200, 600 and 800).

The width range for Khmer is left alone partly because of an apparent
lack of support in fonts.xml for non-normal width fallback fonts.

Note that Noto Sans Khmer UI is left alone because of a baseline issue.
