In preparation for compiling tcg/ only once, eliminate
the all_helpers array. Instantiate the info structs for
the generic helpers in accel/tcg/, and the structs for
the target-specific helpers in each translate.c.
Since we don't see all of the info structs at startup,
initialize at first use, using g_once_init_* to make
sure we don't race while doing so.

`cpu_pc` at this point does not necessary point to the current
instruction (i.e., the wait instruction being translated), so it's
incorrect to calculate the new value of `cpu_pc` based on this. It must
be updated with `ctx->base.pc_next`, which contains the correct address
of the next instruction.
This change fixes the wait instruction skipping the subsequent branch
when used in an idle loop like this:
0: wait
bra.b 0b
brk // should be unreachable

The root trace-events only declares a single TCG event:
$ git grep -w tcg trace-events
trace-events:115:# tcg/tcg-op.c
trace-events:137:vcpu tcg guest_mem_before(TCGv vaddr, uint16_t info) "info=%d", "vaddr=0x%016"PRIx64" info=%d"
and only a tcg/tcg-op.c uses it:
$ git grep -l trace_guest_mem_before_tcg
tcg/tcg-op.c
therefore it is pointless to include "trace-tcg.h" in each target
(because it is not used). Remove it.

Currently we have a RXCPU typedef and a RXCPU type checking
macro, but OBJECT_DECLARE* would transform the RXCPU macro into a
function, and the function name would conflict with the typedef
name.
Rename the RXCPU* QOM type check macros to RX_CPU*, so we will
avoid the conflict and make the macro names consistent with the
TYPE_RX_CPU constant name.
This will make future conversion to OBJECT_DECLARE* easier.

With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.
Alternatively you can use a fine-grained dependency, e.g.
target/arm/translate.o: target/arm/decode-neon-shared.inc.c
With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.
The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.
Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files. The editorconfig
file is adjusted.
