Introduce a separate variable that allows the user of the
<pin-keyboard> Polymer element to control the "letter-spacing" attribute
of the input field.

This fixes the flaky issue introduced in https://crrev.com/c/2069324
that was sometimes causing the "letter-spacing" attribute to be not set
on <pin-keyboard>'s input at all. (Presumably, the problem was due to
self-referring to the variable from its var() expression.)

Bug: 1051859
Test: start SAML login using a smart card, type 8 digits in the PIN dialog, verify that all 8 dots fit into the input field but the dots aren't touching each other
