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. Bug: 36855735 Bug: 37997769 Test: manual. built multiple devices and verified that the correct versions of fonts.xml were showing. Change-Id: I8308f0cb3068274bca5ebd25a38cc023babbd69d
