Some progress

USD export: normalize skel joint weights.

Added logic to USDSkinnedMeshWriter to normalize joint weights.

USD skel export WIP.

Fixed armature export logic for writing pose channel
transform samples. Updated skinned mesh writer to
set the joint indices and joint weight attribute
element size to the maximum total weight value
of the deform verts.

Replace uint8* with char* in Ghost API when variable is a string.

Replace integer with bool in Ghost API when only used as boolean.

Replace Ghost integral types with standard fixed width integers.

UV: Increment snapping based on new UV grid types

Since the default UV editor grid has been replaced with a new
subdividing grid and dynamic grid (T78389) has also been implemented,
increment snapping value needs to change according to the grid
configuration in use.

This commit ensures that the increment snapping value is changed
according to the grid dimensions currently in use.
Example - For a NxN grid the increment value is set as 1/N

Added function for consistent socket type label.

Cleanup: Refactor reusable code into functions

New functions for :
* Calculating current zoom factor used for determining the grid
resolution in UV/Image editor
* Calculating grid steps for determining the grid spacings in UV/Image
editor

Also register the type label for node sockets.

Align the socket type UI with the property split.

Check context pointer to avoid crashes.

Context can be NULL, e.g. when building docs or
when searching the bpy API.

Optional labels for nicer socket type names in UI.

Cleanup: Use struct pointer

Replace struct variables to use pointers instead
