Support GraalVM Builds

[johannesduesing]

Is your feature request related to a problem? Please describe.
It is currently not possible to compile the Delphi CLI application using GraalVM. Partial solutions have been discussed and implemented as part of #27, but are not part of any release yet. However, using GraalVM may yield a speedup of up almost 10 (see discussion below #27).

Describe the solution you'd like
Implement a solution that enables GraalVM native builds.

Describe alternatives you've considered
None, as we definetely want to support GraalVM in the future (see #27 (comment))

Additional context
None
