Replace tests of ASSERT_ENABLED with ENABLE(ASSERT).

Replace tests of ASSERT_ENABLED with ENABLE(ASSERT).

Also replaced tests of SECURITY_ASSERT_ENABLED with
ENABLE(SECURITY_ASSERT).

This change helps ensure that Assertions.h has been properly included,
and paves the way toward enabling asserts in Release builds of Blink.

This is almost completely a search-and-replace operation. The only
exceptions are Image.h, where previous work indicated an #include of
Assertions.h was needed; RawResource.h, which contained an incorrect
use of SECURITY_ASSERT_ENABLED; and Assertions.h, which has been
converted to define ENABLE_ASSERT instead of ASSERT_ENABLED and
similar for the security assert.

Tested with a debug build of Chromium and verified that a manually
inserted failure under ENABLE(ASSERT) was triggered.

Adam: per our offline discussion, here's the mechanical search-and-replace for
your rubber stamp.

This incorrect #ifdef usage was caught by this change as it won't compile any
more.
