Show a deprecation message if run under IDA for 32-bit

Hex-Rays has begun to sunset the version of IDA for 32-bit binaries. Instead,
users should migrate to the 64-bit adress aware version, which supports both.

BinDiff and BinExport will follow suit and stop distributing plugins for
IDA for 32-bit binaries. As a side effect, this makes our build infrastructure
simpler and installation packages smaller.

For more information, see https://hex-rays.com/products/ida/news/8_1/.
