add back dojo.config.forceBgIframe flag

[bill]

[20187] added a dojo.config.forceBgIframe flag, but [20473] removed it, opting instead to create the iframe automatically in more cases.

However, sometimes the iframe is needed even on chrome and safari (on windows). I don't want to just add it unconditionally though because it will weigh things down, especially mobile.

So, should add back the flag (or a flag) to explicitly control whether or not there's an iframe.

See also #11822.

Turn on BackgroundIframe for chrome too, to help with applets. Also add has() flag to control whether or not BackgroundIframe shows. Starting in 2.0 I'd like it to be false by default.

Fixes #11822, #16268 !strict.

Rename bgIframe to config-bgIframe. Also moving BackgroundIframe test from dijit/general-modules to dijit/infrastructure-modules. Refs #16268 !strict.

Backport of has("bgIframe") flag to 1.8 branch. Didn't change the default conditions when it's true though, so if you want to get the background iframe on Chrome then you need to manually set it, like test_bgIframe.html does. Refs #11822, #16268 !strict.
