Debugger: Guard QML inspector inserts against a missing parent

The QML inspector attached a child object to a parent as soon as
m_debugIdToIname named that parent, without checking the parent's
WatchItem still existed in the Locals tree. When it did not (never
inserted, or dropped by a tree rebuild), WatchHandler::insertItem hit
its parent assertion, once per object -- flooding the log and making
the IDE unresponsive during QML debugging.

Only take the direct-insert path when the parent is actually present;
otherwise defer the object and re-fetch the parent, as already done for
parents unknown to m_debugIdToIname.

Verified with a churning Qt Quick app under the debugger: the assert
burst at watchhandler.cpp:2245 disappears with the guard.

ProjectExplorer: fix crash on shutdown

During shutdown the DeviceManager may already be gone (static d reset in
~DeviceManager) while background tasks still touch the device-file
hooks. Bail out instead of dereferencing a null d.

FakeVim: Fix stall on word motion over a non-BMP character

Word motion advanced the cursor with "position() + 1", a raw one code
unit step. On a non-BMP character such as an emoji (stored as a UTF-16
surrogate pair) that lands inside the pair; QTextCursor snaps back, so
the position never progresses, atDocumentEnd() never becomes true and
the motion loop spins forever, freezing the editor. Use movePosition(),
which steps over a surrogate pair as a unit and always advances.

Debugger: Fix corrupted tracepoint capture expressions

tracepointExpression() stored self.output (the list put() appends
to) directly as a captured expression's value, instead of
self.takeOutput() (the join-and-reset helper every other call site
already uses, e.g. reportResult()). Every custom "{expression}"
capture in a message tracepoint printed Python's raw list repr on
the wire instead of valid MI text - affects the real, existing
pseudo-tracepoint feature (GdbEngine::handleTracepointHit()), not
just experimental code.

Found via a GdbImpl regression test driving the same shared dumper
script directly.

TextEditor: Fix block cursor corner past end of line

The block (overwrite/FakeVim) cursor is drawn as a filled rectangle
one space wide, and the character under it is additionally inverted
via a selection range. Past the end of the text there is no character
to invert, but the selection highlight was still added. That highlight
is a touch shorter than the filled block and, on an empty line or past
the last character, wider than it, so their union left an unpainted
notch at the bottom-right corner of the cursor.

Skip the selection highlight when the cursor is past the end of the
text; the plain filled block is then drawn cleanly.
