Yang Guo 5cc9f9bc5f Revert "[stack-trace] Include API functions in Error.stack stack trace" 
This reverts commit 3dd5661204.

Reason for revert: causes leak tests in blink layout tests to fail: https://ci.chromium.org/p/chromium/builders/ci/WebKit%20Linux%20Trusty%20Leak/34295

Steps to reproduce:
- Build blink_tests with following GN args
is_component_build = false
is_debug = false
strip_absolute_paths_from_debug_symbols = true
- Run
third_party/blink/tools/run_web_tests.py --additional-expectations third_party/blink/web_tests/LeakExpectations --time-out-ms 48000 --enable-leak-detection external/wpt/wasm/webapi/body.any.html

Original change's description:
> [stack-trace] Include API functions in Error.stack stack trace
> 
> This CL extends Error.stack to include frames of functions declared
> with the C++ FunctionTemplate API. For example, "print" in d8.
> 
> Two changes are necessary:
>   - HandleApiCall and friends need to go through an BUILTIN_EXIT frame
>     instead of an EXIT frame. The existing stack-trace machinery will
>     then pick up FunctionTemplate frames without additional changes.
>   - Turbofan doesn't go through HandleApiCall, but instead uses an
>     ASM builtin to enter FunctionTemplate functions. A "marker"
>     frame state is needed to include these frames in the stack trace.
> 
> Note: This CL only includes these frames in Error.stack,
> but not (yet) in the stack-trace API (v8.h).
