## Description of change
* when custom DLLs are detected (`d3d9.dll`) print out some basic data
from the PE header
* for our own NVIDIA DLL stubs, add manifest files to identify ourselves
* as a bonus, when DLL hooks are loaded from `-k`, print DLL info there
as well
This is mainly to detect when DXVK is in use.

## Description of change
When raising fatal errors via `log_fatal`, also show a modal popup.
Update instances of `log_fatal` where the message was too long to fit.
## Testing
Tested various failure conditions.
## Description of change
When the game library fails to load, recursively iterate its import
table to narrow down the missing library.
If the dependency is a commonly missing one, give the user a hint on
where to find it.
## Testing
System with an AMD GPU and LDJ-010 IIDX:

## Description of change
Log a message if d3d9.dll (and friends) are found in the game root or
the modules directory.
This is to help with troubleshooting in cases where the user is unaware
that d3d9 is being used to inject other DLLs (e.g., ifs_layeredfs), or
when DX9 reimplementation is causing issues / crashes (e.g., dxvk).
## Testing
Observed the new messages being logged in both modules / root directory.
## Link to GitHub Issue, if one exists
#304
## Description of change
Complain loudly about DLL conflicts. Show warnings for each DLL that
exists in both modules directory and the root.
This is not based on LoadLibrary hooks, just enumerating DLLs via
filesystem access.
Deliberately not using `log_fatal` since these are not necessarily going
to crash the game. Some people just love to have messy installs and if
the game booted fine before, it should continue to boot.
## Testing
Tested with/without `-modules`, with/without duplicate DLLs.
