[HBD] Fix the misleading no-fallback placeholder message in BLOCK mode.

[HBD] Fix the misleading no-fallback placeholder message in BLOCK mode.

Previously, if the user had the BLOCK Content Setting (either from
Policy or just from user setting), the no-fallback placeholder for
HTML5 By Default would still say "Click to enable Flash".

This was misleading because that would not work. This updates the BLOCK
no-fallback placeholder to say "Flash is blocked" and "Flash is blocked
by enterprise policy" (if blocked by policy).
