The `Script::source_url` field holds the value of the magic
`//# sourceURL` comment if found, and the `Script::name` field is
supposed to hold the actual name of the resource (as provided by
the embedder ideally), in case of Chromium that's supposed to be
the URL (in case of Node.js it's often the local path).
Using `source_url` worked by chance so far, but for loading DWARF
symbol files correctly we need the initiator (which we pick from
the embedderName of the Script as reported to DevTools). More
importantly, the partial handling of `//# sourceURL` in V8 is a
layering violation and causes trouble in DevTools, i.e. when users
put relative paths here. So as part of refactoring and correctifying
the handling of `//# sourceURL`, we need to make sure that the embedder
provided name (the URL in case of Chromium) is always stored in the
`Script::name` field.

This changes the behavior of SetBreakpointForScript to find more
accurate break positions.
Previously, setting a breakpoint would only consider the shared
function info that contained the requested position for setting a
breakpoint. More intuitively, a breakpoint should not necessarily
be set in a function that contains the position, but in the closest
breakable location that comes after the position we requested.
To achieve this we:
1. find the shared function info of the inner most function
that contains the requested_position.
This function's end position is used to find other shared function
infos in step 2.
2. search for all shared function infos that intersect with the
range [requested_position, inner_most_function.break_position[.
3. From the shared function infos extracted in 2, find the one
that has the closest breakable location to requested_position.

We can't properly guarantee that the interrupt is served from inside
the irregexp engine (it could happen before or after). Without that
guarantee, the test is prone to flaking. It's not very useful in
general, since it essentially only tests that the
CHECK(!regexp_stack_->is_in_use()) in regexp-stack.cc exists.
The real fix is to support reentrancy.

This is the biggest chunk, including
- all of src/wasm,
- torque file for wasm objects,
- torque file for wasm builtins,
- wasm builtins,
- wasm runtime functions,
- int64 lowering,
- simd scala lowering,
- WasmGraphBuilder (TF graph construction for wasm),
- wasm frame types,
- wasm interrupts,
- the JSWasmCall opcode,
- wasm backing store allocation.
Those components are all recursively entangled, so I found no way to
split this change up further.
Some includes that were recursively included by wasm headers needed to
be added explicitly now.
backing-store-unittest.cc is renamed to wasm-backing-store-unittest.cc
because it only tests wasm backing stores. This file is excluded from
no-wasm builds then.

The definition of {wasm::WasmCode} will not be available in no-wasm
builds, hence avoid any accesses to WasmCode for logging.
Drive-by: Inline enumeration of wasm modules for logging of existing
code, to avoid another #if.

They were using a fixed offset of pc+2, but since the instructions can
be multiple bytes long (leb128 encoded), it should be using *len.
Drive-by fix to add missing instructions to wasm-module-builder.js.

Lazy native accessors require special handling to rewrite
the accessor into a data property, so transition to a
slow handler for this case.

This is a reland of a8b61ef521
The main reason for the revert was not related to this CL and was fixed
with https://crrev.com/c/2739646
In addition debug output in d8.test.verifySourcePositions was removed
due to TSAN complaints.
Original change's description:
> [sparkplug] Change bytecode offset mapping and introduce iterator.
>
> Previously, we recorded pairs of (bytecode offset, sparkplug pc) to
> create a mapping of bytecode offset <-> sparkplug pc.
> These pairs were only recorded after builtin/runtime calls.
> In preparation for deoptimizing to Sparkplug, we need a more precise
> mapping.
> With this CL, we record positions for every bytecode. Instead of storing
> a pair of (bytecode offset, sparkplug pc), we store only the pc,
> calculating the bytecode offset from the index in the mapping table.
> For easier use an iterator to access the mapping is introduced.
>
> Drive-by: Reduce sampling interval in cpu-profiler cctest to get rid of
flaky failures.
