[Martin Storsjö via lldb-commits]

https://github.com/mstorsjo created https://github.com/llvm/llvm-project/pull/159345

This avoids the following warnings from Clang:

    ../../lldb/source/Host/windows/Host.cpp:324:3: warning: default label in switch which covers all enumeration values [-Wcovered-switch-default]
      324 |   default:
          |   ^
    ../../lldb/source/Host/common/File.cpp:662:26: warning: cast from 'const void *' to 'char *' drops const qualifier [-Wcast-qual]
      662 |           .write((char *)buf, num_bytes);
          |                          ^
