[Feature Request] Add MD5 checksum verification status icons

Description

Under Core Information, a check icon indicates if the stock BIOS filename is correct. However, for the MD5 checksum, it only displays the value without any visual icon to indicate whether the used file's checksum is correct or incorrect. This is relevant because OpenBIOS can be used to replace the stock BIOS file.

Feature request

Add visual status icons to indicate whether the MD5 checksum is correct or incorrect.

Use case and status icons to indicate when the MD5 checksum is correct

1. Place the stock bios file (scph5501.bin) into your RetroArch system directory.
2. Start RetroArch
3. Main Menu → Information → Core Information

Use case and status icons to indicate when the MD5 checksum is incorrect

1. Add external OpenBIOS to the system directory

• Obtain an upstream OpenBIOS binary (e.g., from PCSX-Redux):

# Download the latest dev AppImage from https://distrib.app/pub/org/pcsx-redux/project/dev-linux-x64
./PCSX-Redux-HEAD-x86_64.AppImage --appimage-extract
cp squashfs-root/usr/share/pcsx-redux/resources/openbios.bin ./scph5501.bin
# Check MD5
md5sum scph5501.bin
# 75d12438e62a4c338cf417bb6d7aa96d  scph5501.bin

• Place the renamed file (scph5501.bin) into your RetroArch system directory.

2. Start RetroArch
3. Main Menu → Information → Core Information

Relevant log output

Start at RetroArch's Main Menu → Information → Core Information screen and compare the existing stock BIOS filename status indicator with the MD5 value display. Trace how this information is exposed for Beetle PSX, Beetle PSX HW, PCSX ReARMed, and SwanStation; done means the screen visibly distinguishes matching and non-matching MD5 checksums for the affected cores.
