In this CL I implement streaming compilation for WebAssembly,
as described in the design doc I have sent out already.
In this implementation the decoding of sections other than the

Eventually all decoding should happen in the background. I
think it is acceptable to do the decoding on the foreground
thread for now because I have finished it already, and
decoding in the background would add even more complexity to
this CL.

In our internal code, we should only use pending exceptions. They will
be converted to scheduled exceptions on the API boundary.
Hence, the ErrorThrower just sets a pending exception; it should never
have to think about scheduled exceptions. The new
ScheduledErrorThrower inherits from ErrorThrower and reschedules any
pending exceptions in its destructor (turning them into scheduled
exceptions).
In some situations, there might already be a scheduled exception, e.g.
when calling other API methods (v8::Value::Get). In this case, the
ErrorThrower should also not set another pending exception. For the
reasons mentioned above, this can only be handled in the
ScheduledErrorThrower, which is used the API methods.
This fixes one DCHECK failure and one TODO about scheduled exceptions
if no instance can be created, because the start function throws.

The error thrower did allocate the exception at the moment the error was
detected. For async compilation, this meant in another step than when
it was actually thrown. Since the HandleScope of the exception already
died at that point, this would have lead to memory errors.
With this refactoring, we only store the information needed to generate
the exception in the ErrorThrower, and only generate the exception
object once it is actually needed.
With regression test.

This CL implements consume_leb by using checked_read_leb.
It also refactors a few things:
1) It removes error_pt, which was only avaible in checked_read_leb.
2) It renames the error method to errorf, since it receives a format
string. This also avoids a name clash.
3) It implements sign extension directly in checked_read_leb instead of

V8 is collecting a growing amount of fuzzers, all of which take substantial
space on the bots and in chromium build archives. This CL improves that
situation by allowing component (shared library) builds for almost all fuzzers.
The parser fuzzer is handled as an exception since it would require exporting a
large number of additional functions.
A component build results in about a 50-100x improvement in file size for each
fuzzer (~50M-100M to around 1.1M).

Implements:
- WebAssembly object,
- WebAssembly.Module constructor,
- WebAssembly.Instance constructor,
- WebAssembly.compile async method,
- and Module and Instance instance objects.
Also, changes ErrorThrower to support capturing errors in a promise reject.
Since we cannot yet compile without fixing the Wasm memory, and cannot validate a module without compiling, the Module constructor and compile method don't do anything yet but checking that their argument is a suitable BufferSource. Instead of a compiled module, the hidden state of a Module object currently is just that buffer.

This will be needed during debugging to know function boundaries within
the wasm module bytes, and to extract the bytes for a single function
to disassemble it.

The usage of __attribute__((format(x, y)) was either wrong or missing from multiple functions, leading to erroneous formats. This CL:
- Imports PRINTF_FORMAT macro from Chrome's src/base/compiler-specific.h.
- Uses it appropriately.
- Imports Chrome's base/format_macros.h mainly to fix size_t formats (further cleanup could be done).
- Fixes a bunch of incorrect formats.
