  -----------
  [lldb] Bounds check minidump location descriptors (#223911)

MinidumpParser::GetModuleUUID sliced the file with the RVA and DataSize
taken straight from a module's CvRecord. ArrayRef::slice asserts, but a
build without assertions still reads out of bounds.

Route both through MinidumpFile::getRawData, which range checks in 64
bits, and log the error rather than returning a slice that looks valid.
