Read version from VERSION file in CMake

[KyleFromNVIDIA]

Description

Rather than hard-coding the RAPIDS version throughout CMake code, have a single CMake module that reads it from VERSION and provides it as a variable.

Need to also change https://github.com/rapidsai/cudf/blob/branch-24.02/ci/release/update-version.sh

[bdice]

Can we remove the lines from ci/release/update-version.sh that update files that are now templated on this variable?

edit: Rob was faster :D

[bdice]

This should target branch-24.04, since 24.02 is in burndown (code freeze starts tomorrow).

Can you provide PR description please?

Great change! Is there an issue tracking this change for all RAPIDS repositories?

None that I know of. I'd also like to add a linter to https://github.com/rapidsai/pre-commit-hooks that warns you if you hard-code a version number (or updates it if the file is configured to allow hard-coding.)

Edit: here's the comment I posted that promped this: https://github.com/rapidsai/ops/issues/2549#issuecomment-1908638851

Should most likely create a tracking issue on https://github.com/rapidsai/build-planning/

[KyleFromNVIDIA]

I've created rapidsai/build-planning#15.
