Before this, only the [[ProxyHandler]] was set to null during revocation
of the Proxy through either the v8::Proxy::Revoke() or the
Proxy.revocable() API. To be consistent with the spec, the Proxy's
target is set to null as well. This change should not be observable
through JS, since the check for if the Proxy is revoked should always
use the handler. But the changed value is exposed through the public
v8::Proxy::GetTarget() API, which is used by the inspector API and
Node.js.
Also included is a much more comprehensive test for Inspector's support
for Proxy, which prior to this commit did not work as intended.

Now that we have an API to request code cache, we want to decouple
compilation from serialization. As a first step, we will add CompileEager
option (used when we want to produce full code cache) and
DeferredProduceCodeOption to NoCacheReason. This is so that we can
properly bucket the compilation time and collect statistics about the
cache behaviour. Once, blink and node start using the new API, we can
remove the code to produce code cache from the compilation.

We collect instance type statistics in FatalProcessOutOfMemory into an
array, which is allocated to the max instance type value. While we want
to leave space to ensure new instance types do not affect constants in
the API, we can be more frugal.
We currently serialize 350 maps into the startup/context snapshot. Even
if we assign a distinct instance type to each of these maps, we would
still have more than enough to spare with this change.

Like CSP flag 'unsafe-eval', which communicates if both JS source
files and WASM binary files may be compiled, this CL adds a similar
flag for the compilation of WASM binary files.
That is, a WASM binary file will be compiled only if the new flag is
defined, or the flag for 'unsafe-eval' allows it. These flags are
implemented as callback functions on the isolate. The callbacks get a
(CSP) context, and a string, and returns the corresponding value of
the flag.
Both callbacks are initialized with the nullptr, and is used to
communicate that no CSP policy is defined. This allows this concept to
work, independent of it running in Chrome.
It also does a small clean up in api.cc to use macro CALLER_SETTERS,
instead of explicit code when appropriate.

Rather than having a single script compilation timer, split it into
multiple timers depending on the state of the (blink-owned) code cache
and (v8-owned) complation cache. This is intended to replace both the
script compilation time timer, and the compilation heuristic enum.
Also keep track of why blink might not want us to produce (or consume) a
code cache, and split the compilation timer on this as well.
Note, there is currently no timer for streaming sources, so these won't
show up in the histograms.
