Types of changes

• Bug fix (a non-breaking change which fixes an issue)
• New feature (a non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

As reported by @koresar in #5509, the memory usage is printed too early for the dev command. This pr makes it optional to print memory usage in the banner and adds a simple show mem usage method for printing with consola.info

Thank you. I appreciate!

Please change it to show usage after renderer loaded resources

[pimlie]

render:resourcesLoaded is called twice and render:done is never called, will have a look at your other suggestion of adding another hook

[pimlie]

This is getting way too complicated for a simple and not precise feature anyway, but I cant get a 'render:resourcesDone' hook as proposed by @pi0 to work because isModernReady already returns true on the first call to build:resources from webpack/builder which causes the new resourcesDone hook still to be called twice.

I can fix it probably but then I need to change the isReady / isModernReady behaviour in renderer so they only return true when their respective build:resources hook has been called from webpack/builder. Or do you have a better idea?

I like the idea of showing the correct memory usage in dev, thanks for the PR <3

Actually we need to wait for the renderer to be ready (since the bundleRenderer will take some memory usage).

We need indeed to add a new hook for this, I believe together we will find a nice way to do so :)

This is breaking banner.js
