HMR disposal

[alvarosabu]

Atm HMR disposal is not working as expected. Meshes are duplicated and this could lead to performance issues on large scenes.

Also not nice for DX. User needs to reload everytime.

This one is pretty tricky.

Desired solution.

Renderer, scene and object follow a disposal flow when HMR hits

Update: I realized that HMR works differently if the changes come from the experience <script> tag (reloads js) rather than the <template> (doesn't)

We will need to only dispose of scene objects when changes come from the template.

I opened a ticket on vitejs/vite-plugin-vue#103

I opened a ticket on vitejs/vite#12097 with a possible solution, it will need to be done with 2 PRs, one for Vite and another for Vue Plugin
