Deprecate Ambiguous Vue component tracking options

[lforst]

Description

In our Vue SDK, there are two ways how users can set the component tracking-relevant options:

Sentry.init({
	// dsn...
	trackComponents: true,
	timeout: 1000,
	hooks: ['init', 'mount', 'update']
})

Or

Sentry.init({
	// dsn...
	tracingOptions: {
		trackComponents: true,
		timeout: 1000,
		hooks: ['init', 'mount', 'update']
	}
})

As pre-work to #5907 we want to deprecate one of the ambiguous options. It is part of this task to figure out which one to remove or whether to go for an entirely different API. There is the idea to move the option into the vueIntegration.

• Update docs (Instruct to use the recommended way of using Vue component tracking sentry-docs#11917)
• Deprecate older variants (feat(vue): Deprecate configuring Vue tracing options anywhere else other than through the vueIntegration's tracingOptions option #14385)
• Implement migration path for nuxt (feat(nuxt): Expose vueIntegration #14526)
• Update docs for nuxt (Streamline nuxt component tracking sentry-docs#11993)
• Deprecate older variants for nuxt (feat(nuxt): Deprecate tracingOptions in favor of vueIntegration #14530)

@s1gr1d would you mind taking over this task for nuxt?
