Initiliaze global context only once per test suite. Test data relevant
to the respective tests is still allocated and freed with every test
case.
Also, `scene->nodetree` will be deprecated in a future PR, so use
`material->nodetree` to test embedded trees instead.

Use snake style naming for all the kernel nodes functions.
Omit kernel prefix in the names since of the using namespace.
Use full forms of the terms
('iter' -> 'iterator', 'ntree' -> 'node_tree', 'rem' -> 'remove', ...).

Some tests would access system paths somehow, which implicitely creates
the static `m_systemPaths` variable, but would not explicitely call
`GHOST_DisposeSystemPaths` at the end to release it.
Noticeable when disabling the `WITH_TESTS_SINGLE_BINARY` option.
Move all header file into namespace.
Unnecessary namespaces was removed from implementations file.
Part of forward declarations in header was moved in the top part
of file just to do not have a lot of separate namespaces.

The idea is to allow iterating over e.g. all ID usages of a node from a
whole nodetree, using the same generic handling as existing 'whole ID'
`foreach_id` code.
This is necessary in some cases wher a sub-data needs to processed
independently from any 'owner ID', e.g. in some copy/paste handling.
This is a pre-requirement for proper fix of nodes copy/paste (see
e.g. #120103).
