[3.14] GH-130397: remove special-casing of C stack depth for WASI (GH-134469) (GH-134547)

GH-130397: remove special-casing of C stack depth for WASI (GH-134469)

Removed special-casing for WASI when setting C stack depth limits. Since WASI has its own C stack checking this isn't a security risk.

Also disabled some tests that stopped passing. They all happened to have already been disabled under Emscripten.
(cherry picked from commit ad42dc1909bdf8ec775b63fb22ed48ff42797a17)
