Add ML-KEM to speed.cc, bump AWSLC_API_VERSION to 30 (#1817)

### Description of changes: 
Bump AWSLC_API_VERSION to 30 so speed.cc can tell which library versions
have ML-KEM support. Add the ML-KEM benchmark for all future versions of
AWS-LC that support it.

### Testing:
Ran speed locally:
```
./tool/bssl speed -filter ML-KEM
Did 85000 ML-KEM-512 keygen operations in 1002430us (84794.0 ops/sec)
Did 84000 ML-KEM-512 encaps operations in 1008991us (83251.5 ops/sec)
Did 70000 ML-KEM-512 decaps operations in 1009795us (69321.0 ops/sec)
Did 48000 ML-KEM-768 keygen operations in 1014221us (47327.0 ops/sec)
Did 52000 ML-KEM-768 encaps operations in 1011926us (51387.2 ops/sec)
Did 44000 ML-KEM-768 decaps operations in 1012853us (43441.6 ops/sec)
Did 30000 ML-KEM-1024 keygen operations in 1004572us (29863.5 ops/sec)
Did 34000 ML-KEM-1024 encaps operations in 1012471us (33581.2 ops/sec)
Did 29000 ML-KEM-1024 decaps operations in 1021323us (28394.5 ops/sec)
