Fixes#26637.
Fixes#19900.
The viewport_size returned by get_viewport_size was previously incorrect, being half the correct value. The function is renamed to get_viewport_half_extents, and now returns a Vector2.
Code which called this function has also been modified accordingly.
This PR also fixes shadow culling when using ortho cameras, because the correct input for CameraMatrix::set_orthogonal should be the full HEIGHT from get_viewport_half_extents, and not half the width.
It also fixes state.ubo_data.viewport_size in rasterizer_scene_gles3.cpp to be the width and the height of the viewport in pixels as stated in the documentation, rather than the current value which is half the viewport extents in worldspace, presumed to be a bug.
We used a lock signals in the signal_map while emitting, because it was
not allowed to disconnect them while being emitted.
We used that lock to check if we where deleting an object during signal
emission.
Now that we allow to disconnect signals while they are being emitted, if
an object first disconnects, then gets deleted we can't know that a
signal was being emitted during the destructor.
This commit adds a new `_emitting` boolean member to Object to be set
while emitting and checked in the destructor, while removing the old
signal lock which is now unused.
Now that projects are loaded asynchronously, some projects in the
list may be displayed before their icon is done loading. This is
especially common on slower hardware.
In such cases, this makes the project manager display a loading
placeholder instead of the default project icon.
This should speed up rendering slightly. While the project manager
is hardly demanding, this may help on high refresh-rate displays
or very slow machines.

Not using `or_greater` as there *is* a max size value that the current
implementation can accept. If using e.g. size 6000 with
FiraSans-Regular.ttf, errors are printed due to failing asserts on a
glyph size that should be within 4096x4096 px.
As our script class parser is error prone, we should not impede the build from continuing because of a parsing error.
This should be reverted in the future once we switch to Roslyn.
I improved dictionary description to ad some real life examples and expand on it a little bit so person who never seen dictionary can understand it better seeing them for a first time here.
I also added note about the way to compare dictionaries as it can catch people of guard because common assumption is that it works the same as comparing Arrays when it does not.
