Synchronously loading plugins cannot load dependencies properly

[slotthhy]

Plugins that load synchronously that use dependencies provided by Dalamud (such as SharpDX) will fail to load if they utilize these dependencies in their constructor.

Repro: https://github.com/lmcintyre/Dalamud1158

When the above plugin is built and loads at some time after startup, it executes properly:

2023-03-14 13:09:09.079 -04:00 [INF] [LOCALPLUGIN] Loading Dalamud1158.dll
2023-03-14 13:09:09.240 -04:00 [DBG] [Dalamud1158] Device: 1EC8DDD1380 Context: 1EC8DDDC2E8
2023-03-14 13:09:09.240 -04:00 [INF] [LOCALPLUGIN] Finished loading Dalamud1158.dll

However, if the plugin is allowed to load synchronously on startup, the following error occurs:

Note that this error occuring during a sync plugin load seems to prevent any other plugins from utilizing the library.
