This is an attempt to fix
https://gitlab.com/qemu-project/qemu/-/issues/2208
("PC is not updated for each instruction in TCG plugins")
I have only updated target/{i386,arm} so far, but basically all
targets need updating for the new callbacks. Extra points to
anyone who sees how to avoid the extra code duplication. :-)

tcg: Introduce INDEX_op_plugin_pc
accel/tcg: Set CPUState.plugin_ra before all plugin callbacks
