fix: Crash on exit when using custom font from file (#1815)

Browse Source 
### Problem description
WerWolv/ImHex#1814

### Implementation description
1. Remove the flag that wrongly tells `ImFontAtlas` that it owns font
data, and remove that parameter from the function signature entirely
since now it is always `false`.
2. Rename `takeAtlas` to `getAtlas` since it no longer transfers
ownership as of b652565b57.
