Switch to Vue without runtime compiler

What does this MR do?

This allows us to ship a much smaller build of Vue in production and forces folks to use Vue SFC with templates rather than defining templates in HAML which is prone to XSS due to an additional layer of indirection. We are already linting against new usage of this pattern with our eslint rule: @gitlab/no-runtime-template-compiler

We still support compilation from Strings in Jest tests though.
