Reduced block interface & SANITIZER, NOPLUGIN, EMBEDDED changes to CMakeLists.txt

[RalphSteinhagen]

Compile-Time Performance Optimisations and Simplifications

This is a follow-up of PR345.

• reduced different Block construction variants in Block, Graph, BlockWrapper, and BlockRegistry
• simplified some lambda-heavy templating (using clang's -ftime-trace)
• follow-up of minor fixes
• temporarily reverted to using BasicSetting implementation
• added NOPLUGINS flag to by-pass the plugin system in favour of faster compile-times and when runtime or Python wrapping APIs are not requrired e.g. for compile-time only flow-graphs or for CI runners
• Added New CMake Options:    - NOPLUGINS: Disables plugins to reduce compile-times and by-pass runtime- and Python-wrapper API.    - EMBEDDED: Enables embedded mode for size optimization, automatically enabled for MinSizeRel build type.    - TIMETRACE: Enables Clang's -ftime-trace for time-trace information during compilation.    - ADDRESS_SANITIZER: Enables address sanitizer for memory error detection.    - UB_SANITIZER: Enables undefined behavior sanitizer for detecting undefined behavior.    - THREAD_SANITIZER: Enables thread sanitizer for detecting data races.
