Improve documentation related to physics collision shapes
- Document using convex decomposition in the editor.
- Mention that "trimesh" is synonymous with a concave collision shape.
- Add performance hints for each collision shape.

<brief_description>
Defines a 2D collision polygon.
</brief_description>
<description>
Provides a concave or convex 2D collision polygon to a [CollisionObject2D] parent. Polygons can be drawn in the editor or specified by a list of vertices. See also [ConvexPolygonShape2D].
In the editor, a [CollisionPolygon2D] can be generated from a [Sprite2D]'s outline by selecting a [Sprite2D] node, going to the [b]Sprite2D[/b] menu at the top of the 2D editor viewport then choosing [b]Create CollisionPolygon2D Sibling[/b].

<member name="build_mode" type="int" setter="set_build_mode" getter="get_build_mode" enum="CollisionPolygon2D.BuildMode" default="0">
Collision build mode. Use one of the [enum BuildMode] constants.
</member>
<member name="disabled" type="bool" setter="set_disabled" getter="is_disabled" default="false">
If [code]true[/code], no collisions will be detected.
</member>
<member name="one_way_collision" type="bool" setter="set_one_way_collision" getter="is_one_way_collision_enabled" default="false">
If [code]true[/code], only edges that face up, relative to [CollisionPolygon2D]'s rotation, will collide with other objects.
</member>
<member name="one_way_collision_margin" type="float" setter="set_one_way_collision_margin" getter="get_one_way_collision_margin" default="1.0">
The margin used for one-way collision (in pixels). Higher values will make the shape thicker, and work better for colliders that enter the polygon at a high velocity.
</member>
<member name="polygon" type="PackedVector2Array" setter="set_polygon" getter="get_polygon" default="PackedVector2Array()">
The polygon's list of vertices. The final point will be connected to the first. The returned value is a clone of the [PackedVector2Array], not a reference.

<constants>
<constant name="BUILD_SOLIDS" value="0" enum="BuildMode">
Collisions will include the polygon and its contained area.
</constant>
<constant name="BUILD_SEGMENTS" value="1" enum="BuildMode">
Collisions will only include the polygon edges.
