tests: add fuzz testing on core functions (issue #1462)
This commit introduces fuzz testing, for now on core functions, with 4 new targets that are built on demand with CMake option `ENABLE_FUZZ` (build of these tests is disabled by default): - weechat_core_calc_fuzzer - weechat_core_crypto_fuzzer - weechat_core_string_fuzzer - weechat_core_utf8_fuzzer
