1308fc69c5 [AutoDiff] Simplify conditions enabling differentiable programming. (#30765)
Previously, two conditions were necessary to enable differentiable programming:
- Using the `-enable-experimental-differentiable-programming` frontend flag.
- Importing the `_Differentiation` module.

Importing the `_Differentiation` module is the true condition because it
contains the required compiler-known `Differentiable` protocol. The frontend
flag is redundant and cumbersome.

Now, the frontend flag is removed.
Importing `_Differentiation` is the only condition.

eae4c5eece [AutoDiff upstream] @differentiable function type sema (#30648)
Add type checking for `@differentiable` function types:
- Check that parameters and results conform to `Differentiable`.
- Implicitly conform parameters and results whose types are generic parameters
  to `Differentiable`.
- Upstream most of the differentiable_func_type_type_checking.swift test from
  `tensorflow` branch. A few function conversion tests have not been added
   because they depend on the `@differentiable` function conversion pipeline.

Diagnose gracefully when the `Differentiable` protocol is unavailable because
`_Differentiation` has not been imported.

Resolves TF-823 and TF-1219.

6dd557a557 [AutoDiff] NFC: garden tests. (#30588)
Add test/AutoDiff/lit.local.cfg: run tests only when `differentiable_programming`
is enabled in lit. With this, individual tests no longer need
`REQUIRES: differentiable_programming`.

Move multi-functionality SIL tests from test/AutoDiff/SIL/Serialization to
test/AutoDiff/SIL.

Garden test filenames.
