CBMEM console: Fix and enhance pre-RAM support
Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can do CBMEM console in bootblock and romstage. Kconfig forces it to zero if _BASE is unset or we cannot do CAR migration on x86. Add CBMEM console to bootblock, except for x86. Only one of bootblock and romstage clears the pre-RAM buffer. To start with empty console log on S3 wakeup, ramstage now clears previous contents of CBMEM buffer if there was no pre-RAM buffer. Unify Kconfig variable naming. TODO: ARM configurations do not define PRERAM_BUFFER_BASE values.
