Keith Rothman fe4608386e Split nextpnr.h to allow for linear inclusion. 
"nextpnr.h" is no longer the god header.  Important improvements:

 - Functions in log.h can be used without including
   BaseCtx/Arch/Context. This means that log_X functions can be called
   without included "nextpnr.h"

 - NPNR_ASSERT can be used without including "nextpnr.h" by including
   "nextpnr_assertions.h".  This allows NPNR_ASSERT to be used safely in
   any header file.

 - Types defined in "archdefs.h" are now available without including
   BaseCtx/Arch/Context.  This means that utility classes that will be
   used inside of BaseCtx/Arch/Context can be defined safely in a
   self-contained header.

gatecat 7922b3bfc4 Replace DelayInfo with DelayPair/DelayQuad 
This replaces the arch-specific DelayInfo structure with new DelayPair
(min/max only) and DelayQuad (min/max for both rise and fall) structures
that form part of common code.

This further reduces the amount of arch-specific code; and also provides
useful data structures for timing analysis which will need to delay
with pairs/quads of delays as it is improved.

While there may be a small performance cost to arches that didn't
separate the rise/fall cases (arches that aren't currently separating
the min/max cases just need to be fixed...) in DelayInfo, my expectation
is that inlining will mean this doesn't make much difference.

gatecat c7c13cd95f Remove isValidBelForCell 
This Arch API dates from when we were first working out how to
implement placement validity checking, and in practice is little used by
the core parts of placer1/HeAP and the Arch implementation involves a
lot of duplication with isBelLocationValid.

In the short term; placement validity checking is better served by the
combination of checkBelAvail and isValidBelForCellType before placement;
followed by isBelLocationValid after placement (potentially after
moving/swapping multiple cells).

Longer term, removing this API makes things a bit cleaner for a new
validity checking API.
