Feat: Semantic versioning support for Definitions (#6648)
* feature: Add Semantic versioning to KubeVela Definitions

Fixes https://github.com/kubevela/kubevela/issues/6435
Fixes https://github.com/kubevela/kubevela/issues/6534

Changes:
- Adds an optional "Version" field for all Definition Specs.
- Adds the following new validations to Webhooks for Definitions:
	- Validate the "Version" field follows Semantic versioning.
	- Dis-allow conflicting versioning fields ( Name annotation, Spec.Version)
- Adds the following new validations to Webhooks for Application:
	- Dis-allow the use of both the "publishVersion" & "autoUpdate" annotations.
- Enahnce "multiStageComponentApply" feature to support auto updates.

Boy Scout Changes:
- Fixes Plugin e2e tests broken by the fix for 6534.
- Fixes the dryRun and livediff commands to respect the "-n" namespace flag.
- Fixes the Application ValidationWebhook to respect the "-n" namespace flag.
