When loading a PE/COFF target, the associated PDB file often wasn't found. The executable module contains a path for the associated PDB file, but people often debug from a different directory than the one their build system uses. (This is especially common in post-mortem and cross platform debugging.) Suppose the COFF executable being debugged is `~/proj/foo.exe`, but it was built elsewhere and refers to `D:\remote\build\env\foobar.pdb`, LLDB wouldn't find it. With this change, if no file exists at the PDB path, LLDB will look in the executable directory for a PDB file that matches the name of the one it expected (e.g., `~/proj/foobar.pdb`). If found, the PDB is subject to the same matching criteria (GUIDs and age) as would have been used had it been in the original location. This same-directory-as-the-binary rule is commonly used by debuggers on Windows. Differential Review: https://reviews.llvm.org/D84815
