adaptive_cloth: gui for `edge_length_max` and `aspect_ratio_min`

Merge branch 'master' into soc-2021-curve-fillet

More changes and fixes to pass normals around separately from MVert

Knife: Cut along edges to reposition cut start more easily

After receiving feedback on devtalk, users expressed they wished to be able to cut along an edge so they could make further cuts from a new position along the edge.
This also adds the potential to implement snapping to a given distance along an edge.

adaptive_cloth: parameter name from `size_min` to `edge_length_min`

Cleanup: improve code clarity

Addresses D12341 review.

Fix: Knife cut vertex sometimes placed in space

When using relative constrained angle mode along an edge which has a face hidden from view, if a cut is added it can sometimes place the previous cut vertex in space, away from the edge.
This was caused by knife_snap_edge_constrained not working correctly when a cut is constrained along the edge it was started from.

Fixed by adding a quick check.

Initial changes to move normals out of MVert

adaptive_cloth: AdaptiveMesh: dynamic face sizing (for curvature)

Compute the dynamic face sizing with respect to curvature and do eigen
decomposition of the final sizing to add constraints with respect to
edge lengths and aspect ratio.

adaptive_cloth: AdaptiveMesh: calculate derivative

Calculate derivative of the given float3s with respect to the uv space
coordinates of the given face.

adaptive_cloth: Mesh: Node: get normal

float2x3 and float3x2: transpose and multiplication with intern file

Transpose and multiplication requires access to the other structure as
well, this cannot be done through header files only, at least not
easily. So separate implementation files for each with the respective
functions that are required.

float3x2: constructor through columns of the matrix

float2x2: transpose

float2x2: inverse

float2x2: constructor through direct values of the matrix

float2x2: constructor through columns of the matrix

Cleanup: replace defines with static const in walk/fly operators.

No functional changes.
