Add lookaside IPsec functional tests. Known vector tests and
combined mode framework is added.

Known vectors are outbound vectors based on
https://datatracker.ietf.org/doc/html/draft-mcgrew-gcm-test-01

The vectors are updated to have sequence number as 1 & L4 checksum
computed correctly. And they have following properties,
1. ESP
2. Tunnel mode
3. IPv4
4. IPv4 tunnel

Known vector tests for inbound operation would generate test vectors by
reversing outbound known vectors. The input_text would become encrypted
packet and output_text would be the plain packet. Tests would then validate
the operation by comparing against plain packet.

Combined mode tests are used to test all IPsec features against all ciphers
supported by the PMD. The framework is introduced to avoid testing
with any specific algo, thereby making it mandatory to be supported. Also,
testing with all supported combinations will help with increasing coverage
as well.

Four test cases use combined mode,
1. Display algo coverage and basic in + out tests
2. Negative test for ICV corruption
3. IV generation
4. UDP encapsulation

IV generation test case compares IV generated for a batch of packets and returns
failure if IV is repeated.

Upcoming additions,
1. AES-CBC-SHA1-HMAC known vectors & combined mode
2. IPv6
3. Transport
4. Mixed mode (IPv4-in-IPv6 etc, all combinations)

Tested with following PMDs
1. crypto_octeontx2
2. crypto_cn10k
3. crypto_cn9k

Changes in v5:
- Fixed lack of return check with dev_configure_and_start() (comment from Akhil)
- Adjusted patch title and description (comment from Akhil)

Changes in v4:
- Fixed lack of device stop in case capability check fails (comment from Ciara)
- Rebased and updated release notes

Changes in v3
- Added UDP encapsulation tests

Changes in v2
- Dropped outbound known vector tests as lookaside protocol would require IV
  generated by PMD. The tests would be introduced with spec change to allow user
  to specify IV.
- Added IV generation tests
- Minor fixes in combined mode tests to handle multiple packets

Anoob Joseph (2):
  test/crypto: add lookaside IPsec cases
  test/crypto: add combined mode IPsec cases

Tejasree Kondoj (3):
  test/crypto: add lookaside IPsec ICV corrupt test case
  test/crypto: add IV gen cases for IPsec
  test/crypto: add UDP encapsulated IPsec test cases

Applied to dpdk-next-crypto

Thanks.
