Subject: [PATCH] Budget Web bundle bytes per source package

Add soft/hard budgets for the code each package contributes to the shipped
Web JavaScript, measured with `bundlePackage`:

- @shopify/checkout-kit: 18 / 24 KiB (currently 15.9 KiB)
- @shopify/checkout-kit-protocol: 16 / 20 KiB (currently 14.3 KiB)
- @shopify/checkout-kit-telemetry: 5 / 8 KiB (currently 4.2 KiB)

Requires the `bundlePackage` measurement on the default branch; until then
Size budgets rejects this budget file.

 A budgeted package that no longer contributes bytes reports a missing
 measurement. Remove or rename its budget in the same change. Accepting a
 per-package breach records that package, so the acceptance cannot satisfy
