Delete DummyMesh when RasterizerStorageDummy is Freed

The missing `operator<` definitions caused `Vector::sort()` to fail
sorting those alphabetically by name on Windows (not sure why Linux
isn't affected, I guess GCC/Clang are cleverer and use the operator
from the first struct member).

Mono/C#: Remove script load error about not a Godot.Object

Fix too eager GDScriptFunctionState stack cleanup

Any C# file can be loaded as script and at load
time we don't yet know if it's actually meant to
be used as a script. As such, such an check can
result in a lot of false errors.

If the file is really meant to be used as a
script, an error would be printed later when
attempting to instantiate it any way.

Style: Remove unnecessary semicolons from `core`

[Windows] Add quotes only to the command line arguments with special characters.

Semicolons are not necessary after function definitions or control flow
blocks, and having some code use them makes things inconsistent (and
occasionally can mess up `clang-format`'s formatting).

Removing them is tedious work though, I had to do this manually (regex
+ manual review) as I couldn't find a tool for that. All other code
folders would need to get the same treatment.
