ishell@chromium.org 1067c6accc [ext-code-space] Add InterpreterEntryTrampolineForProfiling builtin 
... - a code range size agnostic version of InterpreterEntryTrampoline
builtin. The new builtin is fully compatible with the default version
and used as a template for creating interpreter entry trampoline
Code objects when --interpreted-frames-native-stack is enabled.

This CL introduces a new assembler option "position_independent_code"
which affects the way builtin calls are generated.
This mode is enabled only for InterpreterEntryTrampolineForProfiling.

Motivation:

* InterpreterEntryTrampoline uses RelocInfo::CODE_TARGET for calling
  other builtins which requires the code range to be small enough to
  allow PC-relative jumps/calls between Code objects. This is the
  reason why --interpreted-frames-native-stack was not supported on
  arm and might not work on arm64 because the code range is bigger
  than the max PC-relative distance for call/jump instructions.
  The new builtin calls other builtins via builtins entry table which
  makes the code fully relocatable and usable for any code range size.

* RelocInfo::CODE_TARGET requires a target code to be materialized
  as a Code object which contradicts the Code-less builtins goal.

* The --interpreted-frames-native-stack is rarely used in the wild but
  we have to pay the price of deserializing InterpreterEntryTrampoline
  builtin as a Code object which consumes address space in the code
  range and thus limits the number of V8 isolates that can be created
  because of code range exhaustion. Now the pointer compression cage
  becomes the limiting factor instead of the code range.

* We can remove complicated logic of Factory::CopyCode() and respective
  support on GC side.
