[OMSI] Preparing Code generation for C

Preparing OpenModelica/OMCompiler master for generating OMSUs with `simCodeTarget=omsic`.

- Compiler/Template/CodegenCFunctions.tpl
  - Use new C data structure for generated code for OMSUs.
  - Added function `crefOMSI` and C basic data types depending on `simCodeTarget`.
- Compiler/Template/CodegenUtil.tpl
  - Added `varKinds` `LOOP_ITERATION()` and `LOOP_SOLVED()`. Those are used for solving algebraic loops.
- Compiler/Template/CodegenUtilSimulation.tpl
  - Added function `template fullPathPrefix(SimCode simCode)` to get `fullPathPrefix` from `SimCode`. Used for generating OMSUs in specified folder.
  - Return `equationIndex` for `SES_ALGEBRAIC_SYSTEM`.
  - Added dump functions for `derivativeMatrix` and `OMSIFunction`.
- Compiler/Template/SimCodeTV.mo
  - Added optional `OMSIData` to `SimCode`
  - Added typeview for new records `OMSIData`, `SES_ALGEBRAIC_SYSTEM`, `DerivativeMatrix`, `OMSI_CONTEXT`, `LOOP_ITERATION`, `LOOP_SOLVED`
  - Added typeview for new functions `getLocalValueReference`, `localCref2SimVar`, crefPrefixPre
- Compiler/Stubs/SimCodeUtil.mo
  - Added `function localCref2SimVar<A,B>`, `function getValueReference`, `function getLocalValueReference<A>`

- Compiler/Template/CodegenOMSIC.tpl
  - Functions for code generation only used for `simCodeTarget=omsic`
- Compiler/Template/CodegenOMSIC_Equations.tpl
  - Mainly functions for code generation for equation code. Used for C and C++
- Compiler/Template/CodegenOMSI_common.tpl
  - Shared template functions, used for `simCodeTarget=omsic` and `simCodeTarget=omsicpp`
