Add an option to pass user data to the allocator functions. It is common to
do this so that the host embedder can pass a struct as user data and access
that struct from the allocator, which gives the host embedder the ability to
do things such as track allocation statistics within the allocator.
Compile with `cmake -DWASM_MEM_ALLOC_WITH_USER_DATA=1` to enable
the option, and the allocator functions provided by the host embedder should
be like below (an extra argument `data` is added):
void *malloc(void *data, uint32 size) { .. }
void *realloc(void *data, uint32 size) { .. }
void free(void *data, void *ptr) { .. }

When building LLVM, if multiple SDKs are installed in `/Library/Developer/CommandLineTools/SDKs`,
headers from multiple SDKs are picked, generating build errors as describe here:
#1758.
Without disabling the bound checks (i.e. -DWAMR_DISABLE_HW_BOUND_CHECK=1)
when building `iwasm`, the `-g=127.0.0.1:1234` parameter makes the runtime crash.
Update the document to avoid the issues.

Refine AOT exception check in the caller when returning from callee function, remove the exception check instructions when hw bound check is enabled to improve the performance: create guard page to trigger signal handler when exception occurs.
