This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.
It will also allow to override the interrupt handling for certain CPU
families.

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions.
The field may not be called "env" due to it being poisoned.

Combine this with breakpoint handler registration, guarding both with
tcg_enabled() to suppress also TCG init for qtest. Rename the handler to
xtensa_breakpoint_handler() since it needs to become global.

Introduce realizefn and set realized = true in cpu_xtensa_init().

There was no CPU_SAVE_VERSION defined, so neither "cpu_common" VMState
nor cpu_{save,load}() were registered. Their implementation was no-op.
Therefore there is no backwards compatibility to keep, so mark XtensaCPU
as unmigratable at device level.

In XEA1, the Options for Memory Protection and Translation and the
corresponding TLB management instructions are not available. Instead,
functionality similar to the Region Protection Option is available
through the cache attribute register. See ISA, A.2.14 for details.

ATOMCTL SR controls s32c1i opcode behavior depending on targeted memory
type. See ISA, 4.3.12.4 for details.

Make the include paths for cpu-qom.h consistent to allow using XtensaCPU
in cpu.h.
Turn cpu_init macro into a static inline function returning
CPUXtensaState for backwards compatibility.

Move XtensaConfig-independent code from cpu_xtensa_init() into a
QOM initfn, as a start.

Move code from cpu_state_reset() into QOM xtensa_cpu_reset().
To avoid moving reset_mmu() and dependencies, make it non-static.

Embed CPUXtensaState as first member of XtensaCPU.
Let CPUClass::reset() call cpu_state_reset() for now.
