[support/ld] Unify linker scripts.
Add new common.inc, which is common_rom.inc with some
DEFINED(_FLASH_BUILD) usages thrown in to allow for RAM builds. It
also uses a new REGION_RODATA region alias for read-only data.
Move section .USER_FLASH to REGION_RODATA. This means it lives in RAM
under RAM builds. Although this might be surprising, not doing so
would make RAM builds useless.
Modify the individual board linker scripts to properly set
REGION_RODATA and _FLASH_BUILD before calling out to common.inc.
Delete common_rom.inc, common_ram.inc, common_header.inc, in favor of
common.inc. This should fix RAM builds on all boards.
