Adopt ESP32 test driver to pw_unit_test output (project-chip#34114)

* Adopt ESP32 test driver to pw_unit_test output

* Link ESP32 tests with ToString(CHIP_ERROR, ...) wrapper

* Fix segfault

* Fix CHIP stack initialization when running tests

* [ESP32] Do not delete default event loop

The PlatformManagerImpl::_InitChipStack() does not create default event
loop, so the PlatformManagerImpl::_Shutdown() shall not delete it.

* Fix MultiBufferEncode test with pool allocator

* Include TestWriterReserve test only for heap allocator

* Disable buffer use check for LWIP pool
