Revert vector icon CLs.

Revert vector icon CLs.

This reverts the following commits:

ac1592c73bdd24eca2ea3e591e8f7b199627e6e7: "mandoline: Fix aura build for android."
5490bafef2f11416bed41ad8017a6db500c67345: "Split vector icon commands into separate files aggregated at build time."
33b823af3e63287dbe850c253ae97593411d4f43: "Introduce some util code for drawing vector assets."

Reason for revert is 33b823af3e63287dbe850c253ae97593411d4f43, which
is one of the suspects for having broken browser_tests on Mac builders:
