Updates for Chrome 137 beta

[Elchi3]

The @openwebdocs BCD collector project v10.12.13 found new features shipping in Chrome 137 beta which was released last week. Currently, the collector covers about 90% of BCD, so the following list might not be exhaustive. Also, if a feature is in Chrome Canary/behind origin trials/enrollment, it is not considered here.

With this PR, BCD considers the following 13 features as shipping in Chrome 137:

• api.ImageData.pixelFormat
• api.Selection.direction
• api.Selection.getComposedRanges
• css.properties.reading-flow
• css.properties.reading-flow.flex-flow
• css.properties.reading-flow.flex-visual
• css.properties.reading-flow.grid-columns
• css.properties.reading-flow.grid-order
• css.properties.reading-flow.grid-rows
• css.properties.reading-flow.normal
• css.properties.reading-flow.source-order
• css.properties.reading-order
• webassembly.jspi
