feat(core): add --exclude-task-dependencies flag (#27137)

<!-- Please make sure that your commit message follows our format -->
<!-- Example: `fix(nx): must begin with lowercase` -->

<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
There is no option to exclude dependent tasks when running Nx.

## Expected Behavior
There is a flag, `--exclude-task-dependencies`, to exclude task deps
from running. This is inline with other tools:

- [dotnet
cli](https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-build#:~:text=%2D%2Dno%2D-,dependencies,-Ignores%20project%2Dto)

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->

Fixes #18053
