exec: Remove accel/tcg/ from include paths

When TCG is enabled, the accel/tcg/ include path is added to the
project global include search list. This accel/tcg/ directory
contains a header named "internal.h" which, while intented to
be internal to accel/tcg/, is accessible by all files compiled
when TCG is enabled. This might lead to problem with other
directories using the same "internal.h" header name:

$ git ls-files | fgrep /internal.h
accel/tcg/internal.h
include/hw/ide/internal.h
target/hexagon/internal.h
target/mips/internal.h
target/ppc/internal.h
target/s390x/internal.h

As we don't need to expose accel/tcg/ internals to the rest of
the code base, simplify by removing it from the include search
list, and include the accel/tcg/ public headers relative to the
project root search path (which is already in the generic include
search path).

plugin-gen: add module for TCG-related code

We first inject empty instrumentation from translator_loop.
After translation, we go through the plugins to see what
they want to register for, filling in the empty instrumentation.
If if turns out that some instrumentation remains unused, we
remove it.

This approach supports the following features:

- Inlining TCG code for simple operations. Note that we do not
export TCG ops to plugins. Instead, we give them a C API to
insert inlined ops. So far we only support adding an immediate
to a u64, e.g. to count events.

- "Direct" callbacks. These are callbacks that do not go via
a helper. Instead, the helper is defined at run-time, so that
the plugin code is directly called from TCG. This makes direct
callbacks as efficient as possible; they are therefore used
for very frequent events, e.g. memory callbacks.

- Passing the host address to memory callbacks. Most of this
is implemented in a later patch though.

- Instrumentation of memory accesses performed from helpers.
See the corresponding comment, as well as a later patch.
