Per https://tc39.es/proposal-import-assertions/#sec-assert-clause-to-assertions,
import assertions should be sorted by the import assertion [[Key]]s,
in order to prevent hosts from relying on a changing order of the
assertions to determine behavior.

Prior to this change, the assertions were being sorted by pointer. With
this CL, the keys are sorted using a code point ordering so that the
order of the assertions received by the host will be stable and
non-surprising.

This CL also switches the SourceTextModuleDescriptor's ModuleRequestMap,
RegularExportMap, and RegularImportMap to use the code point order
comparison rather than their former shortlex sort.  This change will not
be externally visible, but it seems best to make these consistent.

In order to avoid #including the fairly large ast-value-factory.h
into ast/modules.h, I changed ImportAssertions into a separate class
definition rather than keeping it as a typedef.  The alternative would
be to define a common AstRawStringComparer in ast-value-factory.h and
then #include ast-value-factory.h in both ast/modules.h and
parsing/parser.h so that the ImportAssertions typedef would have a
full, shared definition of the AstRawStringComparer type.

FLAG_disable_write_barriers is a constexpr so the V8_LIKELY macro isn't
necessary. Interestingly, it can also cause clang to warn that the code
is unreachable, whereas without `__builtin_expect()` the compiler
doesn't mind. See for example:

```
constexpr bool kNo = false;

void warns() {
  if (__builtin_expect(kNo, 0)) {
    int a = 42;
  }
}

void does_not_warn() {
  if (kNo) {
    int a = 42;
  }
}
```

Compiling V8 for arm64 with both `v8_disable_write_barriers = true` and
`v8_enable_pointer_compression = false` would trigger this warning.

This CL reverses the count logic for the tiering strategy of the
js-to-wasm wrappers. The initial approach was that calls to each
function were counted up, until a threshold was reached and the function
would tier up. With this CL, each function is assigned a budget of calls
that can be handled through the generic wrapper. Calls are counted down
until the budget is exhausted, which will trigger the tier-up
for the function.

This approach comes with two advantages. Firstly, determining whether
a function's budget is exhausted is as simple as checking the flags set
from the decrement of the budget. Secondly, the code generated by the
generic wrapper does not depend on the specific value of the initial
budget.

The fuzzer is expected to generate a lot of syntax and runtime errors,
and the respective messages just flood the fuzzer output. By always
putting a {TryCatch} scope around the execution, we prevent those
messages from being printed.
At the same time, inspector tests need to properly propagate uncaught
exceptions in the backend to the inspector, and fail on uncaught
exceptions in the frontend.

This CL allows for all these behaviours by extending the
{CatchExceptions} enum and the {TryCatch} logic in the task runner.

Drive-by: Use {base::OS::ExitProcess} instead of the explicit
{fflush} and {_exit}.

Turboprop should tierup to OSR roughly at the same time as TurboFan,
so we wait for kProfilerTicksForTurboPropOSR ticks before OSRing. This
value was incorrect because we OSR after 4 ticks (we increment the ticks
after the tiering up decision). Also, we wait for additional ticks based
on function size. That should also adjust for the lower interrupt budget
on Turboprop.
