[mlir][core] Move InitAll*** implementation into static library.

`InitAll***` functions are used by `opt`-style tools to init all MLIR dialects/passes/extensions.
Currently they are implemeted as inline functions and include essentially the entire MLIR header tree.
Each file which includes this header (~10 currently) takes 10+ sec and multiple GB of ram to compile (tested with clang-19), which limits amount of parallel compiler jobs which can be run.
Also, flang just casually includes this file into one of its headers.

Move the actual registration code to the static libarary, so it's compiled only once.
