console: Add Kconfig to dump pre-bootblock cbmem contents
Pre-bootblock stages (i.e., VBOOT_STARTS_BEFORE_BOOTBLOCK) might not
have the ability to log to the UART, so their console messages are
inaccessible until the boot processes gets into the payload or OS.
This makes it difficult to debug verstage.
This feature will dump the pre-bootblock CBMEM console immediately
after the bootblock console is initialized. I chose to do this in
console_init instead of bootblock_soc_init because I wanted to have the
pre-bootblock contents dumped before the coreboot bootblock starting
message is printed.
BUG=b:213828947
TEST=Boot guybrush with PSP verstage and verify verstage logs are dumped
to the UART.
