blinkbuild: Use NameStyleConverter in enum_for_css_keyword(), enum_for_css_property(), and enum_for_css_property_alias().

We'd like to reduce the usage of _upper_camel_case().

enum_for_css_keyword() and enum_for_css_property() accept a str or a
NameStyleConveter instance as an argument because their multiple
callsites have only strings, and creating NameStyleConveter in callsites
would make the code noisy.

The generated code won't be changed at all.
