1. For SHA AC, use atomic flag to manage its ownership.
(1) Nuvoton SHA AC doesn't support SHA context save & restore, so S/W
SHA fallback has been supported before. To make non-blocking 'acquire'
semantics clearer, introduce 'try_acquire' to substitute for 'acquire'.
(2) No biting CPU due to mechanism above.
(3) No deadlock due to mechanism above.
2. For AES/DES/ECC AC, change to mutex to manage their ownership.
(1) Change crypto-misc.c to crypto-misc.cpp to utilize C++ SingletonPtr
which guarantees thread-safe mutex construct-on-first-use.
(2) With change to crypto-misc.cpp, add 'extern "C"' modifier to CRYPTO_IRQHandler()
to avoid name mangling in C++.
(3) No priority inversion because mutex has osMutexPrioInherit attribute
bit set.
(4) No deadlock because these AC are all locked for a short sequence
of operations rather than the whole lifetime of mbedtls context.
(5) For double mbedtls_internal_ecp_init() issue, it has been fixed in upper
mbedtls layer. So no need to change ecc init/free flow.
This PR addresses the issue of #8124.
It updates and enriches the wifi connection error type to adapt the Network Socket test plan requirement.
In the meantime, it increases the heap size that allows the transmission of larger packet size.
Description
1. Increase heap size in lwipstack\mbed_lib.json to fulfill bursty TCP and UDP transmission requirement.
2. Modify and enrich wifi connection error types in TARGET_AMEBA\RTWInterface.cpp to adapt the decision logic of the wifi test cases.
3. Add new static constants in TARGET_AMEBA\RTWInterface.h, including 'SSID_MAX_LENGTH', 'PASSPHRASE_MAX_LENGTH' and 'PASSPHRASE_MIN_LENGTH' to help verifying the validity of ssid and passphrase.

Add support for the KW41Z side of the RapidIoT platform. This requires the latest
DAPLink binary to be programmed on the RapidIoT platform, binary can be downloaded
from the below link:
https://armmbed.github.io/DAPLink/
Also, the KW41Z side on RapidIoT does not have a serial port connected to the Debug
terminal. Therefore a SerialPassThrough program should be flashed and running on the
K64F side of RapidIoT platform for the mbed tests to pass.
