Build for 64-bit IDE

### Prerequisites

- [x] This improvement has not already been suggested.
- [x] This improvement would be generally useful, not specific to my code or setup.
- [x] This improvement is not related to analysis quality (e.g. new rules, improvements to existing rules), which should be raised on the [SonarDelphi repository](https://github.com/integrated-application-development/sonar-delphi/issues).

### Engine area

Delphi IDE integration

### Improvement description

Build DelphiLint for 64-bit and provide prebuilt 64-bit binaries.

- Update build script to compile for 64-bit as well as 32-bit
- Make any necessary changes for 64-bit compatibility
- Build 64-bit binaries and upload

### Rationale

Delphi 12 and 13 have a 64-bit version of the IDE that is widely available (though it does not have feature parity yet). DelphiLint should provide 64-bit builds so that it can be used across both versions of the IDE.
