Using MGL fork

[Jesus89]

Now we are using the MGL forked bundle directly in this repo (vendor directory). It is a pain to update the bundle manually and also the @carto/mapbox-gl package. We can optimize this.

In carto-vl we use MGL in the tests (render, user, e2e) and the examples.

For the tests, we should use our MGL fork as a devDependency. For the examples, we should use our published MGL package (#270).

In our fork we should keep the master branch updated, so we need to create a carto branch with our PR merged and the package name updated. For our releases, I would use the original version + -N for our updates. Note: do not forget to generate the dist before doing a release.

We have decided to wait until the MGL v0.45.0 stable version to do the acceptance and merge of this PR.
