Fix for accessibility attributed string tests in isolated mode.
https://bugs.webkit.org/show_bug.cgi?id=219419

Reviewed by Chris Fleizach.

Tests:
accessibility/mac/attributed-string-includes-misspelled-with-selection.html
accessibility/mac/attributed-string/attributed-string-does-not-includes-misspelled-for-non-editable.html
accessibility/mac/misspelled-attributed-string.html

Implemented AXIsolatedObject::rangeForPlainTextRange which is needed to
build the attributed string for a given range.
Also Implemented AXIsolatedObject::doAXBoundsForRangeUsingCharacterOffset
and makeRangeVisible as a follow up to the previous patch to support
PlaintTextRanges in isolated tree mode.

(WebCore::AXIsolatedObject::rangeForPlainTextRange const):
(WebCore::AXIsolatedObject::makeRangeVisible):
(WebCore::AXIsolatedObject::doAXBoundsForRangeUsingCharacterOffset const):
