Migrate style spec files from mapbox to maplibre

[wipfli]

This pull request replaces mapbox with maplibre across files in the src/style-spec directory. It also removes the --validate-mapbox-api-supported flag of the gl-style-validate utility, since this is specific to the mapbox.com API. Note that gl-style-validate still works for validating style files in general.

• ✅ confirm your changes do not include backports from Mapbox projects (unless with compliant license)
• ✅ briefly describe the changes in this PR
• include before/after visuals or gifs if this PR includes visual changes

• document any changes to public APIs
• post benchmark scores
• manually test the debug page
• ✅ apply changelog label ('bug', 'feature', 'docs', etc) or use the label 'skip changelog'
• ✅ add an entry inside this element for inclusion in the maplibre-gl-js changelog: <changelog></changelog>
