9d7b0f1c5f [cleanup] Switch to CodeBuilder everywhere
Switch all uses of NewCode and TryNewCode to CodeBuilder and remove these
methods.

NewCode and TryNewCode use a large number of default parameters, which makes
it difficult to use and add any new ones. Large chunks of code were also
duplicated across TryNewCode and NewCode. The previous CL
(https://chromium-review.googlesource.com/c/v8/v8/+/1585736) added a new
CodeBuilder class which allows much simpler building of Code objects.

6cac1382f4 [cleanup] #include heap-inl.h less often
This takes heap-inl.h out of the "Giant Include Cluster".
Naturally, that means adding a bunch of explicit includes
in a bunch of places that relied on transitively including
them before.
As of this patch, no header file outside src/heap/ includes
heap-inl.h.

b89d4249c0 [nojit] Migrate JSEntry variants to builtins
This migrates the JSEntryStub to three dedicated builtins:

JSEntry
JSConstructEntry
JSRunMicrotasksEntry

Drive-by: Tweaks to make the code isolate-independent (e.g. using the
correct macro assembler method to load and store external references
through the kRootRegister).
Drive-by: The context slot on x64/ia32 must be set up after
kRootRegister is initialized, so we first reserve the slot and later
load its value.
Drive-by: Update all remaining comments referencing JSEntryStub.

feb6576177 [unwinder] Add a test for large code objects
Large code objects are allocated in CODE_LO_SPACE on the heap instead of
CODE_SPACE. Add a test that checks that these objects are still
considered 'InV8' according to the unwinder API.

54ded121ce [unwinder] Add bounds checking to the unwinder API
It's possible that we encounter incorrect SP or FP values while
unwinding the stack. One reason is that third-party code like virus
protection may change the stack. If we encounter values for SP or FP
that don't make sense, we should bail out of unwinding and return false.

f4bb38c321 [tools] Add an API for unwinding the V8 stack
This API allows the embedder to provide a stack and PC, FP and
SP registers. V8 will then attempt to unwind the stack to the C++ frame
that called into JS. This API is signal-safe, meaning it does not call
any signal-unsafe OS functions or read/write any V8 state.
