Fix aot relocation symbols not found on windows 32-bit (#3231)

Browse Source 
The symbols in windows 32-bit may start with '_' and can not be found
when resolving the relocations to them. This PR ignores the underscore
when handling the relocation name of AOT_FUNC_INTERNAL_PREFIX, and
redirect the relocation with name "_aot_stack_sizes" to the relocation with
name ".aot_stack_sizes" (the name of the data section created).
