feat(attributes): Add navigation.origin attribute and deprecate SvelteKit routing attributes

[Lms24]

Description

This PR adds a new, generic navigation.origin attribute (analogously to the already existing navigation.type attribute). The purpose is to record the origin route a client-side navigation was started on. This information is already collected by some of our routing instrumentation (like Sveltekit) but in a less than ideal way.

Therefore, this PR also deprecates a few Sveltekit-specific attributes:

• sentry.sveltekit.navigation.type (to be replaced by navigation.type)
• sentry.sveltekit.navigation.from (to be replaced by navigation.origin)
• sentry.sveltekit.navigation.to (no replacement, as it's redundant with span name and url attributes)

PR Checklist

• I have run yarn test and verified that the tests pass.
• I have run yarn generate to generate and format code and docs.

If an attribute was added:

• The attribute is in a namespace (e.g. nextjs.function_id, not function_id)
• I have used the correct value for apply_scrubbing (i.e. manual or auto. Use never only for values that should never be scrubbed such as IDs)

If an attribute was deprecated:

• I've followed the policies described in CONTRIBUTING.md
