  [lldb][core] Fix getting summary of a variable pointing to r/o memory (#139196)

Motivation example:

```
> lldb -c altmain2.core
...
(lldb) var F
(const char *) F = 0x0804a000 ""
```

The variable `F` points to a read-only memory page not dumped to the
core file, so `Process::ReadMemory()` cannot read the data. The patch
switches to `Target::ReadMemory()`, which can read data both from the
process memory and the application binary.
