Port: Unit tests: Add native Keccak x1 and x4 tests

[willieyz]

• Resolves: Port: Unit tests: Add native Keccak x1 and x4 tests #904
• Based on: Unit-test: add consistency tests for mld_poly_uniform*_x1/x4 #855
• Ported from: Unit tests: Add native Keccak x1 and x4 tests mlkem-native#1516

Add unit tests for keccakf1600 x1 and x4 permutation functions that
compare native implementations against the C reference implementation.

• test_keccakf1600_permute: tests x1 permutation when
  MLD_USE_FIPS202_X1_NATIVE
• test_keccakf1600x4_permute: tests x4 permutation when
  MLD_USE_FIPS202_X4_NATIVE
• Expose mld_keccakf1600_permute_c via MLD_STATIC_TESTABLE for testing
