This PR removes the old `nocapture` attribute, replacing it with the new `captures` attribute introduced in #116990. This change is intended to be essentially NFC, replacing existing uses of `nocapture` with `captures(none)` without adding any new analysis capabilities. Making use of non-`none` values is left for a followup. Some notes: * `nocapture` will be upgraded to `captures(none)` by the bitcode reader. * `nocapture` will also be upgraded by the textual IR reader. This is to make it easier to use old IR files and somewhat reduce the test churn in this PR. * Helper APIs like `doesNotCapture()` will check for `captures(none)`. * MLIR import will convert `captures(none)` into an `llvm.nocapture` attribute. The representation in the LLVM IR dialect should be updated separately.
