google/gru: Change UART _Static_assert() condition to #if
_Static_assert() gets evaluated even when the code path it's in is
unreachable (e.g. inside an if (0) block). Unfortunately, Kconfigs that
depend on a disabled Kconfig are always 0, meaning that
CONFIG_CONSOLE_SERIAL_UART_ADDRESS on Gru cannot evaluate to UART2 when
CONFIG_CONSOLE_SERIAL (which it depends on) is disabled. Switch the
condition it is wrapped in to a preprocessor #if so that the
_Static_assert() is not evaluated when building without serial support.
BRANCH=None
BUG=None
TEST=Built and booted Kevin without serial
