feat(types): add type exports for color mode & theme providers

[Pwuts]

Added type export declarations for the CColorModeProvider and CThemeProvider components, for use with TypeScript environments. Rather than declaring them on the central Vue object, the provided types can be imported; an example is below.

import { Inject } from 'nuxt-property-decorator'
import type { CThemeProvides } from '@chakra-ui/vue'

/* ... inside a class component: */
@Inject('$chakraTheme')
theme: CThemeProvides['$chakraTheme'];

For consistency, I have taken the properties chakraColorMode and chakraToggleColorMode out of the Vue interface declaration. They are not injected or set on the main Vue instance, so they shouldn't be declared on it either.

Motivation and Context

A while ago I submitted a PR (#473) adding type declarations for chakra to the main Vue object. This PR is aimed at also providing types for the provided items from the CColorModeProvider and CThemeProvider components, so this package can be used without issue by Vue/Nuxt + TS users.

This PR fixes the last issues of #469 left over after #473.

How Has This Been Tested?

The pre-push tests are failing on the develop branch anyways, so hard to check.
