zephyr: Add chargen command support
This adds support for the chargen command. The command is used to test
the console output to verify that no data has been lost. To do that, it
uses the low level UART APIs, so the normal shell operation is
temporarily suspended while the command is running.
BRANCH=none
BUG=b:177604307
TEST=tested the command in both zerphyr and ECOS builds
