ohos: Provide IME left/right text-of-cursor

Reason for the change:
Huawei tested text entry on the English keyboard and found that
repeatedly typing 'a' produced "AaaAAA..." in the editor. The defect is
the unexpected switch to uppercase 'A'. The expected output is
"Aaaaaa...".

The input method's auto-capitalization relies on reading the text around
the cursor to decide letter case. Without the left/right text-of-cursor
callbacks the input method could not obtain this context and
intermittently re-applied capitalization.

Fix:
Implement OH_TextEditorProxy_SetGetLeftTextOfCursorFunc and
OH_TextEditorProxy_SetGetRightTextOfCursorFunc (executed on a worker
thread). The text before and after the cursor is computed on the Qt GUI
thread (QOhosInputContext::update()) and pushed into a thread-safe
member  (QOhosMutexProtectedValue) owned by the input method proxy.

QDom: Guard against null nodes returned by factory functions

Since the default InvalidDataPolicy changed to ReturnNullNode, the
QDomDocumentPrivate factory functions return nullptr when the input
contains data that is invalid per XML 1.0. QDomBuilder::characters(),
QDomBuilder::skippedEntity() and QDomBuilder::comment() used the
returned node without checking, causing a crash.

Check for nullptr and return false, as startElement() and
processingInstruction() already do.

Pick-to: 6.12
Fixes: QTBUG-148791
