[balance-text] Add a test for `text-indent`

This patch adds a test of `text-wrap: balance` for a block
with `text-indent`.

Note the balancing algorithm is not defined in the spec; it's
UA-defined. But the text in this test can be fully balanced
that it's reasonable to expect any algorithms to pass.

This test hits a `DCHECK` which happens when one of lines
overflows. This `DCHECK` is no longer valid, it was checking
applicable block but now it checks overflow, which is valid,
so removed.
