Hugo Locurcio b087538119
Add an XML schema for documentation 
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.

Each class XML's schema conformance is also checked on GitHub Actions.

<brief_description>
A [Resource] that contains vertex array-based geometry.
</brief_description>
<description>
Mesh is a type of [Resource] that contains vertex array-based geometry, divided in [i]surfaces[/i]. Each surface contains a completely separate array and a material used to draw it. Design wise, a mesh with multiple surfaces is preferred to a single surface, because objects created in 3D editing software commonly contain multiple materials.

<methods>
<method name="create_convex_shape" qualifiers="const">
<return type="Shape" />
<argument index="0" name="clean" type="bool" default="true" />
<argument index="1" name="simplify" type="bool" default="false" />
<description>
Calculate a [ConvexPolygonShape] from the mesh.
If [code]clean[/code] is [code]true[/code] (default), duplicate and interior vertices are removed automatically. You can set it to [code]false[/code] to make the process faster if not needed.
If [code]simplify[/code] is [code]true[/code], the geometry can be further simplified to reduce the amount of vertices. Disabled by default.
</description>
</method>
<method name="create_outline" qualifiers="const">
<return type="Mesh" />
<argument index="0" name="margin" type="float" />
<description>
Calculate an outline mesh at a defined offset (margin) from the original mesh.
[b]Note:[/b] This method typically returns the vertices in reverse order (e.g. clockwise to counterclockwise).
