Add predefined __ROMSTAGE__ and __RAMSTAGE__ macros
This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get predefined in their respective stages by make, so that we have one specific macro for every stage. It also renames __BOOT_BLOCK__ and __VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency. This change is intended to provide finer control and clearer communication of intent after we added a new (optional) stage that falls under __PRE_RAM__, and will hopefully provide some robustness for the future (we don't want to end up always checking for romstage with #if defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) && !defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The __PRE_RAM__ macro stays as it is since many features do in fact need to differentiate on whether RAM is available. (Some also depend on whether RAM is available at the end of a stage, in which case #if !defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be authoritative.) It's unfeasable to change all existing occurences of __PRE_RAM__ that would be better described with __ROMSTAGE__, so this patch only demonstratively changes a few obvious ones in core code. BUG=None TEST=None (tested together with dependent patch).
