Refs #30288 - improves CPUs counter input

In 22fa163731b38f597e4f96e0c0b345518a360b37 we've introduced React
component to implement the counter funcionality.

and effectivelly remove our dependency on the ui.spinner library.

Fixes #32083 - use full Host model in VM template

model to be around.

This builds the Host model instead and passes it to the templates.

Refs #30784 - MemoryAllocation use react helper

In 8a9922fd we've removed `byte_size_f` last usage.
This is moving the byte_size_f to render the React component, to
seamlessly integrate into the form without breaking any plugins that
were possibly still using it....
