web: add zoom in/out for logs#4354

Add buttons next to "Clear logs" to adjust the font size for logs. At a high-level, a CSS custom property (variable) is used to set a % font size for log lines (the absolute font size is set on the container, and the default property value is 100%). This provides an easy and performant way for JS to adjust the log font size, particularly since the actual log CSS is pure CSS from an SCSS stylesheet, not using `styled-components` in React. The scale value is read from/written to local storage under a global (NOT Tiltfile-namespaced) key so that it's persistent and applies to all Tilt sessions. As a bonus, that means it live synchronizes between tabs which is kinda nifty.
