Utils: Do not assert when opening an unreadable remote file

FSEngineImpl::open() soft-asserted via QTC_ASSERT_RESULT when
fileContents() failed on the read path. Reading can legitimately fail at
runtime - e.g. a dangling symlink that the cached file info still
reports as existing, or insufficient permissions - which is not a
programming error. Fail the open gracefully (return false) instead.

Debugger: Fix crash when stopping with a memory editor open

A memory editor (as opposed to a separate memory view) is a BinEditor
service that is also an IEditor and is handed to the EditorManager via
addEditor(), so the EditorManager owns its lifetime. ~MemoryAgent still
deleted that service directly, which left a dangling editor registered
with the EditorManager and crashed shortly after the debugger stopped.

The editor is already taken care of elsewhere: on debugger exit
DebuggerEnginePrivate::cleanupViews() closes or keeps it depending on the
"close buffers on exit" settings, and MemoryAgent::setFinished() clears
the handlers that reference the engine. So ~MemoryAgent must not touch an
editor at all; only a separate view is owned by the agent and deleted
here.

Debugger: Fix use-after-free in DebuggerEngine::gotoLocation()

DebuggerEngine::gotoLocation() calls EditorManager::openEditor(), which
spins a local event loop. If the debug session finishes during that
window, the engine is torn down (qDeleteAll(m_engines) -> ~DebuggerEngine
-> delete d). The code then dereferenced 'd' and 'this' (m_locationMark,
m_breakHandler, m_watchHandler, displayName()), crashing on freed memory.

This is the same reentrancy hazard fixed for BreakHandler::gotoLocation()
in ef7ababba142ef83267d65cee3c49aa621e1db0e, reachable here via the
BreakpointByAddress branch of that function.

Guard the engine with a local QPointer across the re-entrant openEditor()
call and bail out if it was destroyed, so nothing touches freed memory
afterwards.

CMakeProjectManager: Add build preset vendor extension support

Read Qt Creator-specific make step settings from the build preset
vendor extension (qt.io/QtCreator/1.0). This allows staging, iOS
provisioning, clear system environment to be specified in
CMakePresets.json/CMakeUserPresets.json.

Also document the new build preset vendor keys.
