[css-variables] Why we can not use 'var()' function for normal property

'var()' function is limited for custom property only.
Custom properties and normal properties should be treated equally.
Like this:
..foo {
    --wall: 100px;
    padding-bottom: 50px;
..foo .bar {
    margin-top: var(--wall);
    padding-top: var(padding-bottom);

And then we will change this function name to 'value()'.
'customcolor' keyword in [css-color] may be deleted.
