Also deploy mozc_tip64.dll.pdb (google#1081)

One of the biggest challenge while investigating google#1076 is that it has
been reliably reproducible only on certain users' environments. One idea
to accelerate the debugging in such a scenario is to ship debug symbol
file for Mozc TIP DLL (e.g. mozc_tip64.dll) to users. Then we can ask
the reporter to use tools like Process Explorer and Process Hacker to
dump the call stack of the thread that got stuck.

With this commit we actually start deploying mozc_tip64.dll.pdb to
users.

The storage impact looks to be acceptable overall as long as we strip
private symbols [1]. Here are actual values taken in my local
environment.

 * Mozc64.msi: + 584 kB
 * mozc_tip64.dll.pdb: + 6,116 kB

Note that this commit does not fully take care of Bazel build. While the
symbol file is actually deployed, there remain the following known
issues only in Bazel build.

 * private symbols are not yet stripped out.
 * the symbol file name embedded in mozc_tip64.dll is mozc_tip.pdb
   rather than mozc_tip64.dll.pdb.
