rules.h: Add ENV_ macros to detect current architecture
This patch expands the existing ENV_<stage> macros in <rules.h> with a
set of ENV_<arch> macros which can be used to detect which architecture
the current compilation unit is built for. These are more consistent
than compiler-defined macros (like '#ifdef __arm__') and will make it
easier to write small, architecture-dependent differences in common code
(where we currently often use IS_ENABLED(CONFIG_ARCH_...), which is
technically incorrect in a world where every stage can run on a
different architecture, and merely kinda happened to work out for now).
Also remove a vestigal <arch/rules.h> from ARM64 which was no longer
used, and genericise ARM subarchitecture Makefiles a little to make
things like __COREBOOT_ARM_ARCH__ available from all file types
(including .ld).
BUG=None
TEST=Compiled Falco, Blaze, Jerry and Smaug.
