[Android] Intermittent "Font not found" crash when temporary location is cleared during runtime

[greg84]

Description

Issue in Xamarin also applies in MAUI: xamarin/Xamarin.Forms#15012

FontRegistrar assumes that if a font exists in the dictionary then the file exists on disk. It can't make this assumption because the file may be cleared by the OS to save space, or by the user (app clear cache).

It's hard to reproduce this issue, but frequently reported by production apps from several users. See comments on Xamarin issue.

if this gets sorted in maui, it should really get backported to xamarin forms...

@MitchBomcanhao There are workarounds for this issue in XF. See related issue here.
An equivalent fix can most likely be ported from Xamarin.Forms to MAUI.
