c8166827b5 [wasm][profiler] Report source URL and position
So far we reported the script ID, but DevTools ignores that and uses the
source url instead. That url was just set to "wasm ", which the frontend
couldn't make any sense of.
This CL fixes this by passing the source URL to the code create event,
and also setting the position of the code inside the script (i.e.
wasm module).

32b3b70254 [inspector][profiler] Print wasm positions (url, line, column)
We currently report "wasm " as the source URL on all wasm code, with no
position information. This will change in a follow-up CL. To make that
difference visible, extend a test to show the URL and position reported
for wasm code.

a58a5e594e Reland "[wasm] Pass the script ID to code logging"
This is a reland of ab4d9717f2.
The original CL did a std::move before the final use of the NativeModule.
PS2 removes that.

ab4d9717f2 [wasm] Pass the script ID to code logging
We didn't pass a script ID with the code creation events for profiling.
This made DevTools lose the connection to the wasm script, hence
jumping from the profiler entry to the source did not work.

This CL changes the timing of code logging a bit such that the script is
always allocated before logging. In the queue of code to be logged we
then also store the script ID, and finally set it on the {CodeEntry}
object.

a22e8a7003 [wasm] Fix code logging of wrappers
Import wrappers were only logged if logging was enabled during
compilation. If the profiler is enabled later, and regular wasm code is
logged via {NativeModule::LogWasmCodes}, the import wrappers were
missing.
This CL fixes the long-standing TODO, and adds tests which triggered
that code path. Those tests were hanging before because the expected
functions did never appear in the profile.

Drive-by: If {WasmEngine::LogOutstandingCodesForIsolate} detects that
code logging is disabled by now, it should still clear the {code_to_log}
vector.

31b23fcbd8 [wasm][inspector][test] Check for wasm script id
We currently do not report a script ID for wasm code, i.e. the script id
is 0. We cannot just print the script ID itself, as it is considered
unstable. Thus this CL only makes us print whether it is set or not.
In a follow-up CL where we fix setting script IDs for wasm code events
the output will change.

31005b5c7c [wasm][profiler] Fix late enabling of the profiler
We had a test which first enabled the profiler, and then compiled wasm
code. In this case, all code objects were registered correctly and the
profile looked as expected.
This CL extends the test for also test another order: First compile the
wasm code, then enable the profiler. In that case, we were reporting a
wrong debug name of the exported wasm function. The name of that
function is spec'ed to be the string representation of the function
index. But for debugging, we want to see a more meaningful name,
identical to the name we show when reporting the code during
compilation.

This fix requires handlifying the {SharedFunctionInfo::DebugName}
method, because for exported wasm functions, it needs to allocate a new
name on the JS heap.
In order to avoid this allocation where possible, a second variant is
added which returns a unique_ptr directly. This can be used in all
places where the name is just being printed, which turned out to be the
majority of cases ({DebugName().ToCString()}).
