zephyr: enable flash-space optimized defaults
Enable two options by default, CONFIG_SHELL_MINIMAL and
CONFIG_CBPRINTF_NANO.
Together, these cut back on flash space by a bunch:
Before (volteer):
Memory region Used Size Region Size %age Used
FLASH: 258804 B 512 KB 49.36%
SRAM: 63328 B 62 KB 99.75%
IDT_LIST: 0 GB 2 KB 0.00%
After (volteer):
FLASH: 244996 B 512 KB 46.73%
SRAM: 61432 B 62 KB 96.76%
IDT_LIST: 0 GB 2 KB 0.00%
BUG=b:169158406
BRANCH=none
TEST=above flash space reduction
TEST=boot volteer to OS
TEST="help" in uart console now lists all commands
