pw_async2: Use PW_NO_INLINE to prevent coroutine stack allocation

Tests for coroutine allocation failure or non-dispatched coroutines
require dynamic allocation via CoroPromiseBase::operator new. Mark
coroutines used in those tests with PW_NO_INLINE so the compiler cannot
inline their ramp functions and elide heap allocation via HALO, and
remove EnsureNotStackAllocated and coro_test_util.h.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
