Previously we had passed kOnEntryBreakpointPosition as a marker through
the regular SetBreakPointForScript() logic and handled that specially in
WasmScript, however this instrumentation breakpoint is special and gets
in the way of returning more information about a regular breakpoint in
case of crbug.com/700516, so I decided to just isolate that into it's
own method, especially since the only user already special-cases Wasm
anyways.

This CL includes the following changes:
- Avoid using `UniqueRegister` as much as possible
- Try to group opcodes under Binary or Unary when possible

Separate selectors are added to use `UniqueRegister` when necessary
mainly when `Temp` registers are used. This is to make sure temp, dst
and src registers are allocated differently and cannot be overwritten
during codegen.

Some codegen ops had to also be modified to avoid using `Temp`
registers.

If the debugger is disabled for an isolate, we first remove all
breakpoints for that isolate, and then tier up the module (if there is
no other isolate that keeps it tiered down).
During the first step, functions might get recompiled since the
set breakpoints change. This is not needed in case we will tier-up the
module afterwards anyway. It also triggers a DCHECK if we reinstall
debugging code even though the module is already marked "tiered up".

This CL avoids the installation of debugging if the module is not tiered
down, and also slightly modified the condition for installing new code
when tiered-up (to allow overwriting debugging code with non-debugging
code even if it's the same tier).

JSHeapBroker::ReadFeedbackForCall() - it may be that the JSFunction
we read in the feedback vector hasn't been store-ordered and is
therefore unsafe to read. Therefore, we need to call the gc
predicate to ensure safety.

JSFunctionRef::feedback_vector() & raw_feedback_cell() - I was able
to remove the TODO warning about uninitialized data visible from
a direct read of these fields from the background. This is because
we either store-order into those fields, or rely on a prior
store-ordering. Additionally, FeedbackVectorRef and FeedbackCellRef
are never-serialized objects, so their first encounter on the
background thread is fine (we don't need to have seen and
serialized them on the main thread first).

.. and the corresponding map cache.

This cache was only used for CreateArray reductions, thus we mostly
expect to see unmodified JSArray initial maps. These are already
accessible from the native context and don't need to be cached
separately.

We may also see initial maps for custom JSArray subclasses. New map
allocation may be necessary in this case if the requested elements
kind differs from that of the current given initial map. Since we
can't (easily) allocate on the background thread, we skip the
optimization starting with this CL.

This avoids a DCHECK failure if we continue using the Assembler after
code generation abortion. Even though it might not be the best style to
still call methods on the Assembler after abortion, it's not a problem
apart from the firing DCHECK, so we apply this simple fix instead of
making sure to really abort everything immediately.

This is a reland of dcdaf42f. It adds
CPU time metrics to the WasmModuleDecoded (except for streaming),
WasmModuleCompiled and WasmModuleTieredUp events. This can later be used
to provide this information as UKMs or UMAs.
