commit b550792f0f9357f380d501288f368e85d43279b8

chrome: Unship snapshot_blob.bin from Win/Mac/Linux

We are shipping snapshot_blob.bin and v8_context_snapshot.bin with
Chrome for speed up of launching V8 environments.
Beside it, v8_context_snapshot.bin contains all information in
snapshot_blob.bin, and we no longer need snapshot_blob.bin if
v8_context_snapshot.bin is available.

This CL drops snapshot_blob.bin from Chrome for such platforms
to reduce the size of shipping binaries and memory usages.

 Issue 804253  has been merged into this issue.

 Issue 804254  has been merged into this issue.

We replaced snapshot files to improve the performance of launching V8 in Blink.
The new snapshot file is 400-500kB larger than the old one, so this regression is expected.
