We have a number of reports crashing in nvd3d9wrapx.dll when we call `LoadLibraryEx` with
`LOAD_LIBRARY_AS_DATAFILE` to collect PDB information. It seems that nvd3d9wrapx.dll
detours LoadLibraryEx and its detour function has a bug to access an address of nvinitx.dll
even after it's unloaded.
After we landed Bug 1522830, we started to collect the stack information in the content
process, which introduced a chance to meet conditions to hit this crash.
Given that the high volume of crash reports, this patch adds an ad-hoc workaround to add
library info with dummy PDB info instead of calling `LoadLibraryEx`.
