Per https://github.com/godotengine/godot/issues/14553:
Godot stores Basis in row-major layout for more change for efficiently
taking advantage of SIMD instructions, but in scripts Basis looks like and
is accessible in a column-major format.
This change modifies the C++ binding so that from the script's perspective
Basis does look like if it was column-major while retaining a row-major
in-memory representation. This is achieved using a set of helper template
classes which allow accessing individual columns whose components are
non-continues in memory as if it was a Vector3 type. This ensures script
interface compatibility without needing to transpose the Basis every time
it is passed over the script-engine boundary.
Also made most of the Vector2 and Vector3 class interfaces inlined in the
process for increased performance.
While unrelated (but didn't want to file a separate PR for it), this change
adds the necessary flags to have debug symbol information under MSVC.
Fixes#241.
