Remove set_flags_from_command_line_with_usage test (#570)
This commit removes the set_flags_from_command_line_with_usage and puts
it in an example code section instead.

The motivation for doing this is that the test output currently contains
the usage string and all the V8 options which creates a lot of output
when the tests is run regardless if --nocapture is used or not.

Fix runtime assert when hashing module object (#522)
The blanket `std:#️⃣:Hash` impl for instances of `v8::Data` invokes
`v8::internal::Object::GetHash()` but that crashes for `v8::Module`
objects. Use a custom impl that calls `v8::Module::get_identity_hash()`.

Fixes the following runtime assertion:

    # Fatal error in ../../../v8/src/objects/objects-inl.h, line 1043
    # Debug check failed: object.IsJSReceiver().

Add Isolate::[gs]et_microtasks_policy() (#439)
Isolate::run_microtasks() already exists but the microtasks queue
is also flushed on script entry and exit. Some embedders want strict
control over when microtasks run, which is set by the policy.

And deprecate Isolate::run_microtasks(). The corresponding V8 API is
tagged with V8_DEPRECATE_SOON.

Fix the 'heap_limits' test (#430)
After upgrading to V8 8.6.337, with a 20 MB heap limit, the
near-heap-limit callback never gets called before V8 runs out of memory.

It turns out that this test exhibits memory allocation behavior which
produces so little actual garbage that 'scavenge' type garbage
collections make memory usage go up rather than down. Because of this,
V8 runs out of memory in the middle of a garbage collection cycle, after
it has already decided that there's no need to run the near-heap-limit
callback.

The issue is fixed by making sure that some actual garbage is produced
alongside with the retained objects that will eventually fill up the
heap.

Use correct lifetime for TryCatch::exception()/message() return value (#380)
According to v8.h, "the returned handle is valid until this TryCatch
block has been destroyed". This is incorrect, as can be demonstrated
with the test below. In practice the return value lives no longer and
no shorter than the active HandleScope at the time these methods are
called. An issue has been opened about this in the V8 bug tracker:
https://bugs.chromium.org/p/v8/issues/detail?id=10537.

```rust
fn try_catch_bad_lifetimes() {
  let _setup_guard = setup();
  let mut isolate = v8::Isolate::new(Default::default());
  let mut hs = v8::HandleScope::new(&mut isolate);
  let scope = hs.enter();
  let context = v8::Context::new(scope);
  let mut cs = v8::ContextScope::new(scope, context);
  let scope = cs.enter();
  let caught_msg_2 = {
    let mut try_catch = v8::TryCatch::new(scope);
    let try_catch = try_catch.enter();
    let caught_msg_1 = {
      let mut hs = v8::HandleScope::new(scope);
      let scope = hs.enter();

      // Throw exception #1.
      let msg_1 = v8::String::new(scope, "BOOM!").unwrap();
      let exc_1 = v8::Exception::type_error(scope, msg_1);
      scope.isolate().throw_exception(exc_1);
      // Catch exception #1.
      let caught_msg_1 = try_catch.message().unwrap();
      let caught_str_1 =
        caught_msg_1.get(scope).to_rust_string_lossy(scope);
      assert!(caught_str_1.contains("BOOM"));
      // Move `caught_msg_1` out of the HandleScope it was created in.
      // The borrow checker allows this because `caught_msg_1`'s
      // lifetime is contrained to not outlive the TryCatch, but it is
      // allowed to outlive the HandleScope that was active when the
      // exception was caught.
      caught_msg_1
    };
    // Next line crashes.
    let caught_str_1 =
      caught_msg_1.get(scope).to_rust_string_lossy(scope);
    assert!(caught_str_1.contains("BOOM"));

    // Throws exception #2.
    let msg_2 = v8::String::new(scope, "DANG!").unwrap();
    let exc_2 = v8::Exception::type_error(scope, msg_2);
