Yeah, we have no `SBProcess::FindMemory()` API, but we do have a "memory find" command. We want to expose simple memory finds, and complex ones like above:
```
addr_t SBProcess::FindInMemory(SBAddressRange &range, const void *buf, uint64_t size, size_t alignment);
SBError SBProcess::FindInMemory(const SBAddressRangeList &ranges, const void *buf, uint64_t size, SBAddressRangeList &matches, size_t alignment);
```
We then want to plumb this through to the lldb_private::Process plug-ins so we can allow plug-ins to do things more efficiently. Mostly for core files where we could parallelize the memory search.
