Use DEFINE_STATIC_LOCAL in CSSProperty::GetPropertyNameAtomicString

This avoids having a destructor being run when terminating the process.
These destructor could have ordering issues wrt to the destruction of
the AtomicStringTable. Using DEFINE_STATIC_LOCAL also shrinks the binary
a bit. (The android-binary-size bot says -16375 bytes.)

Remove some redundant '\0' characters for some additional (but minor)
savings.
