ARM: move opcode macros to <target/arm_opcodes.h>
Move the ARM opcode macros from <target/armv4_5.h>, and a few Thumb2 ones from <target/armv7m.h>, to more appropriate homes in a new <target/arm_opcodes.h> file. Removed duplicate opcodes from that v7m/Thumb2 set. Protected a few macro argument references by adding missing parentheses. Tightening up some of the line lengths turned up a curious artifact: the macros for the Thumb opcodes are all 32 bits wide, not 16 bits. There's currently no explanation for why it's done that way...
