Fix repeatedly initialize shared memory data and protect the memory's fields (#2673)

Browse Source 
Avoid repeatedly initializing the shared memory data when creating the child
thread in lib-pthread or lib-wasi-threads.

Add shared memory lock when accessing some fields of the memory instance
if the memory instance is shared.

Init shared memory's memory_data_size/memory_data_end fields according to
the current page count but not max page count.

Add wasm_runtime_set_mem_bound_check_bytes, and refine the error message
when shared memory flag is found but the feature isn't enabled.
