Support fallback value of css variables

[TD-LiXiang]

Our project uses fallback value of css variables. For example:

.my-button {
  color: var(--my-var, #FFFFFF)
}

But the regular expression used by happy-dom only recognizes css variables with no fallback value. The Regular expression is:

const CSS_VARIABLE_REGEXP = /var\( *(--[^) ]+)\)/g;

Do we have plans to support fallback value of css variables?
