ohos: fix crash when handling IME cursor movement

The OHOS input context constructed QChar objects from Qt arrow-key
values when processing an IME cursor-movement callback. These special
key values exceed the UTF-16 range and trigger a QChar assertion in
debug builds.

Change the functional-key helper to accept QString text. Pass empty text
for arrow keys, since navigation keys do not generate Unicode text, and
preserve the control-character text for Delete, Backspace, and Enter
using QStringLiteral.

This prevents crashes when an input method moves the cursor, such as
after inserting paired Chinese punctuation.

QCollator/ICU: Use u_errorName() in diagnostic messages

When ICU operations fail in the ICU collator backend, the diagnostic
messages logged the numeric UErrorCode value. Replace the numeric values
with u_errorName(), which provides the name (for example,
"U_FILE_ACCESS_ERROR"), making warnings more explicit.

harmonyos: Remove duplicate includes

This is a preparatory change to normalizing includes in harmonyos
platform code.

There are two instances of duplicated includes:
  1. qohosplatformscreen.cpp: QtGui/qguiapplication.h
  2. qohosplatformwindow.cpp: QtGui/private/qwindow_p.h

These duplicates differ only in having the Qt module prefix (QtGui/) in
the include path. Follow the Qt coding guidelines and remove the ones,
which are missing the Qt module prefix.
