DQCE and DCS primitives are added - disabling the clock in a quadrant and dynamically selecting the clock source accordingly.

With this commit we are finally able to use clock lines 6 and 7 :)

Added examples for Tangnano1k, Tangnano4k, Tangnano9k, Primer20k, Tangnano20k boards.

From the internals: in addition to the well-known fuse tables SHORTVAL and LONGVAL, functions have been added for working with another table - LONGFUSE. It differs in that it describes the fuses of primitives with only one parameter, in contrast to two parameters for SHORTVAL and 16 parameters for LONGVAL.

Until the PR goes through in nextpnr, there will be errors, so we'll wait.

Well, for some time only one version of the examples will be green - until the release of yosys, since there are our changes in main.
