This flag only controls whether d8 installs the signal handler for wasm
traps. Hence it should be a d8-only flag, to avoid confusion if used in
other embeddings.
We just introduced --wasm-enforce-bounds-checks to do what you might
think --no-wasm-trap-handler would do.

This will allow us to refactor those V8 files without being concerned
about potential interference with the security of the trap handler.
This requires the duplication of V8_EXPORT_PRIVATE, the CHECK/DCHECK
macros, and V8_DISABLE_ASAN. The trap-handler specific definitions
are prefixed with "TH_".

Additionally a bug in the wasm-to-C wrapper got fixed, which caused
problems with the thread-in-wasm flag: An invalid effect-chain got
constructed. With the write of the thread-in-wasm flag not being
properly placed in the effect chain, the write got scheduled too late.

In a new test suite: "wasm-api-tests", using a new binary "wasm_api_tests",
powered by gtest/gmock (like unittests).
Also fix a bunch of issues that these tests uncovered, mostly to ensure
that the stack is walkable.
