The last remaining threaded operation in dynamic ratsnest was the
recalculation of the dynamic connectivity map. Because we do not
require any of the extra features of the connectivity map, we can get
away with a lightweight move of the anchors to update the ratsnest. The
resulting connectivity tree is not valid but it is not needed for the
ratsnest, which only needs a list of nets/anchors.
This option removes copper layers from pads and vias where they are not
connected to other board elements. This allows the inner layers to be
more closely routed if the via landing pad is not needed.

We need to be careful in the connectivity system to always use
dyn_cast/dynamic_cast and check the return when dealing with board
items. Getting non-connected items will result in null nets when
propagated.

When running a hit test to check if the anchors are connected, we should
loosen the check for tracks to account for the width. Otherwise
connected anchors can be connected in the system but test positive for
IsDangling()

- CN_CONNECTIVITY_ALGO::ForEachItem
move implementation to header, so that a lambda can be inlined by the
compiler. improves iteration performance x2
- CN_ITEM::Net
move implementation to header, so that it can be inlined by the
compiler.
- CONNECTIVITY_DATA::GetNetItems
don't use std::set to filter out duplicates. use std::unique on sorted
vector. use a bitset to perform type check.
- Added ignore netcode option to CONNECTIVITY_DATA::GetConnectedItems()
- PlaceModule() now ensures the module added to the board (and thus to the connectivity database) has correct bounding box necessary for R-trees to work
- Use recursive connected pad search so that the new net is propagated to all pads

It is possible for an async thread to simply be deferred if not
specifically set to async. In which case, until the return value is
requested, the loop may simply wait.
This minimizes the thread usage, particularly during online actions such
as moving items and routing.
UpdateRatsnest: Minimized the number of atomics by utilizing future
promise. Avoided updating node-less nets. Node-less nets are common in
the dynamic ratsnest because the net vector is created from the board
nets by value but only populated with a subset. So the dynamic ratsnest
calculation always saw every net as dirty and spun up extra threads.
searchConnections: ParallelThreadCount is no longer lower bounded.
Small item counts are handled inline rather than with a separate thread.
Some windows machines seem prone to sleeping for excessive times. When
called in the main thread, this may prevent the system from responding
to Windows 'Are you alive?' calls.
Rather than forcing each thread to iterate over the full nets list to
find the dirty items, we collect the dirty items first before asking the
threads to address them. This prevents thread spinning. We also
amortize the cost of calculating on an 8-net per thread basis rather
than 2.
