feat(imageresizer): show context menu on all supported formats

[yeelam-gordon]

Summary of the Pull Request

Extends Image Resizer's context menu to appear on all image formats that Windows Imaging Component (WIC) supports, not just the hardcoded list. This enables resizing of formats like WebP, HEIC, and other WIC-supported formats.

PR Checklist

• Closes: [Image Resizer] Show "Resize pictures" on all supported formats #1929
• Communication: I've discussed this with core contributors already
• Tests: Added/updated and all pass
• Localization: N/A - no user-facing strings
• Dev docs: N/A

Detailed Description of the Pull Request / Additional comments

Problem

Image Resizer only showed its context menu on a hardcoded list of image extensions (jpg, png, bmp, etc.). Newer formats like WebP and HEIC, which Windows supports via WIC, didn't show the 'Resize pictures' option.

Solution

Added SupportedFormatsRegistry.cs in src/modules/imageresizer/ImageResizerLib/Models/ that:

• Queries WIC for all supported image decoders
• Builds dynamic list of supported extensions at runtime
• Caches results for performance
• Falls back to hardcoded list if WIC query fails

Validation Steps Performed

1. Right-clicked on a WebP image
2. Verified 'Resize pictures' appears in context menu
3. Selected resize option
4. Verified image resizes correctly

Some files were automatically ignored 🙈

These sample patterns would exclude them:

^src/modules/powerrename/unittests/testdata/avif_test\.avif$
^src/modules/powerrename/unittests/testdata/heif_test\.heic$

You should consider adding them to:

.github/actions/spell-check/excludes.txt

File matching is via Perl regular expressions.

To check these files, more of their words need to be in the dictionary than not. You can use patterns.txt to exclude portions, add items to the dictionary (e.g. by adding them to allow.txt), or fix typos.

To accept these unrecognized words as correct, update file exclusions, and remove the previously acknowledged and now absent words, you could run the following commands

... in a clone of the git@github.com:microsoft/PowerToys.git repository
on the issue/1929 branch (ℹ️ how do I use this?):

curl -s -S -L 'https://raw.githubusercontent.com/check-spelling/check-spelling/c635c2f3f714eec2fcf27b643a1919b9a811ef2e/apply.pl' |
