7dbf01afad coap: move mbedTLS config options from component to examples
CoAP component relies on some mbedTLS crypto configuration
options, e.g. DTLS and PSK. These configuration options if
selected, have footprint impact on generic TLS examples like
https_request or https_ota as well.

Footprint of https_request example with/without change is per below:

$ ./tools/idf_size.py new_https_request.map --diff old_https_request.map

<CURRENT> MAP file: new_https_request.map
<REFERENCE> MAP file: old_https_request.map
Difference is counted as <CURRENT> - <REFERENCE>, i.e. a positive number means that <CURRENT> is larger.
Total sizes of <CURRENT>:                                                 <REFERENCE>     Difference
 DRAM .data size:   14796 bytes                                                 14796
 DRAM .bss  size:   23560 bytes                                                 23680           -120

This commit moves relevant config options to CoAP specific examples
and also adds some run time warnings if they are kept disabled.

430b737760 Fix libcoap building with various MbedTLS compile time options
components/coap/port/coap_mbedtls.c:

Add in additional compile time check wrappers for different MbedTLS
configurations.

components/coap/CMakeLists.txt:
components/coap/component.mk:
components/coap/port/coap_notls.c:
components/coap/port/include/coap_config_posix.h:

Add in the ability to compile and run if MbedTLS does not have any TLS
mode enabled.

examples/protocols/coap_client/main/coap_client_example_main.c:

Inform user that MbedTLS Client Mode is required for DTLS if not enabled,
and coaps:// has been requested.
[Lower libcoap library will still error and report this condition]

examples/protocols/coap_server/main/coap_server_example_main.c:

Inform user that MbedTLS Server Mode is required for DTLS if not enabled.
[Lower libcoap library will still error and report this condition]
