f9c4d0008f [explicit isolates] Move remaining roots to ReadOnyRoots
Moves STRUCT_LIST AND ALLOCATION_SITE_LIST into roots.h and adds access
to their associated maps using ReadOnlyRoots.

Also corrects the location of external_map, message_object_map,
empty_script, many_closures_cell, invalid_prototype_validity_cell and
builtins_constants_table which are not in RO_SPACE.

Finally this adds a convenience ReadOnlyRoots(Isolate*) constructor.

e6799023d3 [cleanup] Add a name() helper to Space in heap
There is no point calling AllocationSpaceName manually every time. We
could get rid of AllocationSpaceName entirely, except that the
serializer calls it directly on ints that are casted to AllocationSpace
objects first.

fc683744e5 Re-enable embedded builtins
Enabling once again post-branch point. This CL is expected to come
with major memory improvements and slight performance regressions.

Recent work on performance improvements has focused on x64, hence only
enabling there for now.

e0c3f6d6ca Disable embedded builtins
Embedded builtins have been regressing benchmarks incrementally as
more and more builtins were moved to the embedded blob. This has made
recognition and analysis of other possible performance issues more
difficult.

Let's disable embedded builtins until their performance is at an
acceptable level.

Re-enable embedded builtins now that 67 has branched.

This reverts two CLs:

Disable embedded builtins for M67 branch point

Enable embedded builtins on two bots
https://chromium-review.googlesource.com/c/v8/v8/+/983597

f23e6e8839 [grokdump] Mark embedded builtins builds as non-shipping
Builds with and without embedded builtins (when combined with RO_SPACE
changes) results in different v8heapconst.py. So this marks embedded
builds as non-shipping. When embedded builtins becomes the default then
this non-embedded builds should be marked as non-shipping.

822be9b238 Normalize casing of hexadecimal digits
This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

ffee558e14 [cleanup] use unique_ptr for the DefaultPlatform
With this CL, {CreateDefaultPlatform} returns a unique_ptr to indicate
that the caller owns the returned memory. We had several memory leaks
where the memory of the DefaultPlatform did not get deallocated.

In addition, the {TracingController} of the {DefaultPlatform} also gets
received as a unique_ptr. Thereby we document that the {DefaultPlatform}
takes ownership of the {TracingController}. Note that the memory of the
{TracingController} was already owned by the {DefaultPlatform}, but it
was not documented in the interface, and it was used incorrectly in
tests.

This CL fixes the asan issues in
