x86: Introduce RESET_VECTOR_IN_RAM option
Create a new Kconfig symbol that allows an x86 device to begin execution
when its reset vector is in DRAM and not at the traditional 0xfffffff0.
The implementation will follow later, this is just to setup various
ENV_xxx definitions correctly for the build environment.
