Update Test 2.4

[mcsmonk]

Currently, the first three test cases for 2.4 in the DOC are invalid GET_CAPABILITIES requests with the following flags:

index	NegotiatedVersion	Flags
0	1.1+	CERT_CAP|CHAL_CAP| MUT_AUTH_CAP|KEY_EX_CAP|PSK_CAP|ENCAP_CAP|HBEAT_CAP|KEY_UPD_CAP
1	1.1+	CERT_CAP|CHAL_CAP|ENCRYPT_CAP|MAC_CAP|MUT_AUTH_CAP| ENCAP_CAP|HBEAT_CAP|KEY_UPD_CAP
2	1.1	CERT_CAP|CHAL_CAP|ENCRYPT_CAP|MAC_CAP|MUT_AUTH_CAP|KEY_EX_CAP|PSK_CAP| HBEAT_CAP|KEY_UPD_CAP

1. SPDM_GET_CAPABILITIES_REQUEST_FLAGS_PSK_CAP_REQUESTER | should be added in index 0 and 2 to sync with the documentation.

2. The test case for the first index is a valid request in the current libspdm.

3. Because CAPABILITIES response message is received in case of the first index test, current test structure immediately fail because both host and device have a AfterCapability state

@mcsmonk DMTF/libspdm#2921 requested that CAPABILITIES not fail for the DSP0277 MAC_CAP check. That check was deferred to when KEY_EXCHANGE was initiated. However I forgot to enforce

KEY_EX_CAP - If set, Requester shall support KEY_EXCHANGE request message. If set, ENCRYPT_CAP or MAC_CAP shall be set.

when checking capabilities. So that check needs to be in libspdm.

@jyao1 will fix the documentation issue. I will fix libspdm in DMTF/libspdm#2944.
