components/openssl: refactor openssl debugging and assert function

1. add openssl option at menuconfig
2. remove SSL_ERR to reduce complexity
3. add more functions about debugging and assert

According these, our coders and customers may use and debug the OpenSSL code easily.

menu "OpenSSL"
config OPENSSL_DEBUG
bool "Enable OpenSSL debugging"
default n
help
Enable OpenSSL debugging function.
If the option is enabled, "SSL_DEBUG" works.
config OPENSSL_DEBUG_LEVEL
int "OpenSSL debugging level"
default 0
range 0 255
depends on OPENSSL_DEBUG
help
OpenSSL debugging level.
Only function whose debugging level is higher than "OPENSSL_DEBUG_LEVEL" works.
For example:
If OPENSSL_DEBUG_LEVEL = 2, you use function "SSL_DEBUG(1, "malloc failed")". Because 1 < 2, it will not print.
config OPENSSL_LOWLEVEL_DEBUG
bool "Enable OpenSSL low-level module debugging"
default n
depends on OPENSSL_DEBUG
select MBEDTLS_DEBUG
help
If the option is enabled, low-level module debugging function of OpenSSL is enabled, e.g. mbedtls internal debugging function.
choice OPENSSL_ASSERT
prompt "Select OpenSSL assert function"
default CONFIG_OPENSSL_ASSERT_EXIT
help
OpenSSL function needs "assert" function to check if input parameters are valid.
If you want to use assert debugging function, "OPENSSL_DEBUG" should be enabled.
config OPENSSL_ASSERT_DO_NOTHING
bool "Do nothing"
help
Do nothing and "SSL_ASSERT" does not work.
config OPENSSL_ASSERT_EXIT
bool "Check and exit"
help
Enable assert exiting, it will check and return error code.
config OPENSSL_ASSERT_DEBUG
bool "Show debugging message"
depends on OPENSSL_DEBUG
help
Enable assert debugging, it will check and show debugging message.
config OPENSSL_ASSERT_DEBUG_EXIT
bool "Show debugging message and exit"
depends on OPENSSL_DEBUG
help
Enable assert debugging and exiting, it will check, show debugging message and return error code.
config OPENSSL_ASSERT_DEBUG_BLOCK
bool "Show debugging message and block"
depends on OPENSSL_DEBUG
help
Enable assert debugging and blocking, it will check, show debugging message and block by "while (1);".
