[css-minifier]expand the static calc()

[yisibl]

Describe the feature

Usually the expressions in calc() can be expanded further in order to reduce the number of bytes.

There is a lot of this styles in animate.css:

animation-delay: calc(1s * 2) = animation-delay: 2s

.animate__animated.animate__delay-2s {
  -webkit-animation-delay: calc(1s * 2);
  animation-delay: calc(1s * 2);
  -webkit-animation-delay: calc(var(--animate-delay) * 2);
  animation-delay: calc(var(--animate-delay) * 2);
}

But if there are percentages in calc(), we have to treat them differently and not expand them. see evanw/esbuild#1821
