feat(core)!: move SlickGrid core files directly into the project

[ghiscoding]

• drop slickgrid npm dependency and instead move all files core into the project (mostly because SlickGrid 5.0 is now written in TypeScript, so it is now easier to move into our project and drop external dependency)
• the end goal is to have less depencies but also to get rid of unused code like the SlickGrid AutoSize since we have our own code in our ResizerService, this will hopefully make the build smaller as well. There are other duplicate code elsewhere, so moving the code in the project should help simplify the code and also make it easier to troubleshoot code
• the only downside is that SlickGrid core project never had any unit tests written, so that will decrease the test coverage by quite a lot since none of the core files have tests
• ⚠️ this is a breaking change PR
