Subject: [PATCH] Clear all StaticLayout.Builder fields on pool recycle

When returning a StaticLayout.Builder object to the pool, it is
important to clear everything out. If not, then the object may have
stale state from a previous layout operation. This was causing CTS
test failures and probably other mischief.
