LOG: Mark the file opened by DeserializedDeclsSourceRangePrinter as a text file (#135842)

This PR will fix the following lit failure seeing on z/OS and most likely on Windows:

`FAIL: Clang :: Frontend/dump-minimization-hints.cpp`

Without `OF_TextWithCRLF` flag, a file is treated as binary and is read improperly, at least on z/OS.

Added: 
    

Modified: 
    clang/lib/Frontend/FrontendAction.cpp

Removed:
