Reland of https://chromium-review.googlesource.com/c/v8/v8/+/1795358.
[builtins] Move non-JS linkage builtins code objects into RO_SPACE
Creates an allow-list of builtins that can still go in code_space
including all TFJ builtins and a small manual list that should be pared
down in the future.
For builtins that go in RO_SPACE a Code object is created that contains an
immediate trap instruction. Generally these Code objects are still no
smaller than CODE_SPACE Code objects because of the Code object alignment
requirements. This will hopefully be addressed in a follow-up CL either by
relaxing them or removing the instruction stream completely.
In the snapshot, this reduces code_space from ~152k to ~40k (-112k) and
increases by the same amount.

Previously only Builtins declared TFJ or CPP in builtins-definitions.h
were converted to direct calls in ReduceJSCall. This allows all
builtins with JS linkage to be converted. To facilitate this, it adds
Builtins::HasJSLinkage(id) that returns true for any builtins with
JSTrampolineDescriptor as their call descriptor.
It also ensures that any JS functions installed by the bootstrapper are
also required to have JS linkage to catch early errors.

These are SSE2 instructions that deal with scalar double precision
values, and look like the packed double precision variant of the
instructions, but with a prefix.
E.g. sqrtpd is 66 0F 51, sqrtss is F2 0F 51.
We don't put this in the same list, even though the implementation
is very similar, because SSE2_INSTRUCTION_LIST is used in other
macros which generate AVX versions of this, and that overlaps with
another macro which generates AVX versions of these X-sd instructions.
I will tease this apart and clean it up in subsequent changes.
