runtime(sdc): update syntax to SDC-standard 2.1
Looking into the current standard for Synopsis Design Constraints (SDC)
from their [Technology Access
Program](https://www.synopsys.com/community/interoperability-programs/tap-in.html),
one can see that the current state of the sdc-syntax file is very
outdated as well as short in coverage of keywords.
This commit pursues to add all the missing keywords from the current
standard (Rev. 2.1).
closes: #15281
