Kconfig: Move CONFIG_SYS_[CP]BSIZE to common/Kconfig

Move CONFIG_SYS_CBSIZE (console buffer size) and CONFIG_SYS_PBSIZE
(console print buffer size) out of cmd/Kconfig and in to common/Kconfig.
Create help entries for both which explain their usage and why they are
both not entirely command centric.
