feat: controlProps() and labelProps()

[huntabyte]

This PR introduces two new functions to Formsnap, controlProps and labelProps, which will retrieve a reactive reference to the control/label props from the context provided by the closest <Control> component in the tree.

These functions reduce the amount of boilerplate required for the Control with Formsnap v2.

Before:

This is still an acceptable way of handling this in Formsnap v2 if you prefer.

<Control>
	{#snippet children({ props })}
		<Label>Name</Label>
		<input {...props} bind:value={$formData.name} />
	{/snippet}
</Control>

After:

<Control>
	<Label>Name</Label>
	<input {...controlProps()} bind:value={$formData.name} />
</Control>

or

<Control>
	<label {...labelProps()}>Name</label>
	<input {...controlProps()} bind:value={$formData.name} />
</Control>
