*and* report all "virtual" wasm scripts right when the wasm script is
registered at the inspector.
WasmScript is a subtype of Script, with the cast checking that it is
actually a wasm script.
This layout makes it quite easy to implement functionality that is only
available for wasm scripts, and allows to later directly use the
WasmCompiledModule instead of the i::Script for backing the
debug::WasmScript. We might also add virtual methods to
provide different implementations for GetSourcePosition, Source and
others.
DisassembleWasmFunction now also becomes a method of this class instead
of a static function on the DebugInterface.
The WasmTranslation now uses the new WasmScript type instead of the
Script wrapper, and also registers all virtual wasm scripts immediately
when the wasm script is made public to the inspector (when the wasm
module is created).

If we just call CreateDebugInfo in GetPossibleBreakpoints then we won't call PrepareFunctionForBreakPoints and won't be able to step into this function or pause at breakpoint inside.

This exposes scopes for suspended generator objects by adding a
[[Scopes]] internal property to generator objects, similar to how
scopes for functions currently not on the stack are handled.

Descriptions for (typed)arrays will use parenthesis instead of square brackets
"Array(10)" instead of "Array[10]". This CL also adds size hints to descriptions
of maps and sets.

When disassembling functions for the inspector, we used an internal
text representation before. This CL implements the official text
format like it is understood by the spec interpreter.
Example output:
func $main (param i32) (result i32)
block i32
get_local 0
i32.const 2
i32.lt_u
if
i32.const -2
return
end
get_local 0
call_indirect 0
end

Inspector uses this type for all internal scripts, e.g. injected-script-source.js. Scripts with new type are not reported by remote debugging protocol, frames from them are ignored.

Before, we allocated one script per function per instance, and each
script referenced the wasm instance and the function index. Now we only
allocate one script per compiled wasm module, so the script also only
references this WasmCompiledModule, which causes changes to many interfaces.
Instead of fixing the disassemble API only used via debug.js, I decided
to drop it for now. Some later CL will reintroduce it via
DebugInterface.

Currently function like "() => 239" contains offset 3 as begin of function and 8 as end of function.
This CL changes this to 6 and 9 respectively.

In the asm.js to wasm pipeline, we generate an entry function with
BUILTIN code, but still attached to a TYPE_NORMAL script.
This fix avoids trying to set a breakpoint there, resulting in a crash
on DCHECK(shared->HasDebugInfo()).
Also add two inspector tests to track regressions.
