Bug 1452 - Decouple math functionality to 'com.jogamp.math' to be toolkit agnostic (PMVMatrix, Matrix4f, Vec4f, ..)

Math functionality (PMVMatrix, Matrix4f, Vec4f, ..)
- shall be used toolkit agnostic, e.g. independent from OpenGL
- shall be reused within our upcoming Vulkan implementation
- may also move outside of JOGL, i.e. GlueGen or within its own package to be reused for other purposed.

The 'com.jogamp.opengl.util.PMVMatrix' currently also used to feed in GLUniformData
via the toolkit agnostic SyncAction and SyncBuffer
shall also be split to a toolkit agnostic variant.

An OpenGL PMVMatrix specialization implementing GLMatrixFunc can still exist,
being derived from the toolkit agnostic base implementation.
