[Android] Fix the progress indicator when leaving native pages.

Force a progress update inside of LoadingStateChanged of the delegate.
When navigating between native pages, the load progress was not being
updated, which broke the case where you navigated to a slow page and
clicked a native page link while waiting.  The previous load progress
wouldn't be cleared and the 'x' in the URL bar would remain.

Expand the Keystone tag to contain the system's CPU's bitness and whether a
full installer is desired.

Formerly, the tag identified only the channel that Chrome was on. The tag is
being enhanced to detect the CPU's bitness (adding "-32bit" for 32-bit-only,
non-64-bit-capable CPUs) and whether a full (as opposed to binary diff patch)
update is requested (adding "-full").

CPU bitness detection ought to be a feature of Keystone, but Keystone uses the
NXGetLocalArchInfo to determine the CPU type, and winds up always reporting
"i486". The "-32bit" tag suffix will be present whenever the
"hw.cpu64bit_capable" sysctl name is not found or has value 0. This enables
proper detection of users who are capable of running 64-bit Chrome on the
server side.

When a binary diff patch update application fails in dirpatcher, typically the
result of modifications made to existing installations, the "-full" tag suffix
will be set. On a subsequent update attempt, the server can detect this value
and provide the client with a full updater package, which does not depend on
the existing installation. The "-full" tag suffix is cleared on successful
update installation.
