Client & runtime split release process

[Dinonard]

Description

Split the existing release process into two parts - client & runtime.
They should be independent.

• split runtime & client release
• client release would follow the existing vX.Y.Z semver notation
  • release would still be triggered via tag push same as today
  • only client is built, without runtimes
• runtime release would follow new runtime-XXYY notation (where XX can be expanded)
  • new logic to handle tag & runtime release build
  • only 3 regular runtimes (+ 3 evm tracing runtimes) are built
  • all runtime spec versions would be the same (e.g. we can start with 1000)
