Enhance type checking for function types in loader and improve error handling (#4294)

Browse Source 
Especially when GC is enabled, a valid item of `module->types` needs additional
checks before casting to WASMFuncType.

Also, avoid overflowing if reftype_map_count is 0.

Additionally, correctly set IN_OSS_FUZZ based on CFLAGS_ENV for sanitizer
configuration. Update ASan and UBSan messages for clarity in non-oss-fuzz
environments.
