CMake: add LMS verify-only, small and shake256 sub-options

Browse Source 
CMake wired only the LMS sha256-192 and no-sha256-256 variants, while
autotools --enable-lms also supports verify-only, small and shake256. Add
the three missing sub-options (WOLFSSL_LMSVERIFYONLY, WOLFSSL_LMSSMALL,
WOLFSSL_LMSSHAKE256), emitting WOLFSSL_LMS_VERIFY_ONLY, WOLFSSL_WC_LMS_SMALL
and WOLFSSL_LMS_SHAKE256, and expose them in the generated options.h so the
CMake and autotools LMS configurations match.
