GD-598: Fixing memory leaks on test execution (#599)

# Why
Running tests via CMD line shows a lot of memory leaks at program exit.

# What
- fixed releasing of all singletons
- `func_assert` has problems with lambdas when using inside
`timer.timeout.connect`, converted lambda into function
- Handling of stored asserts in the thread context results in
inconsistency during cleanup
- fixed cleanup on `GdUnitCommandHandlerTest`


## Finally, I have reduced most of the memory leaks nodes, but there are
still `GDScriptFunctionState` orphaned nodes that I can't solve because
these are handled internally by Godot see
[74449](godotengine/godot#74449)

GD-579: Minimize warnings of testsuite resource loading (#587)

# Why
<!-- Enter a clean description why we need this changeset -->


# What
<!-- Describe exactly what you have changed and what the effects are -->

Update README.md

GD-546: Allow to test un-typed values by `assert_that` (#547)

# Why
see #546

# What
- do allow all Variant types for `is_equal` and `is_not_equal` when
using the un-typed `assert_that`
- changed the fixed typed `is_equal` and `is_not_equal` to accept
Variant type

GD-522: Fix shortcuts can't be changed anymore in GdUnit4 settings (#526

)

# Why
The change shortcuts was broken and not able to change it when clicking
on the shortcut settings.

# What
- fixed by moving the shortcut capture scene to the parent and manage
the visibility differently
- fixes also to modulate on the label to have better visualization
animation

GD-503: Rework plugin exit to avoid system crash and memory leaks (#504)

# Why
The plugin has some issues to release resources at Godot exit and result
sometimes in a segmentation fault under Linux

# What
- fix `remove_child` on `free_instance` to be called deferred now
- removed the temporary `free_fix` workaround
- fix orphan nodes in `GdUnitTestDiscoverer`
- introduce a new flag to call deferred on `free_instance` at plugin
exit
