Tim Ruffing 222ecaf661 Merge bitcoin-core/secp256k1#1284: cmake: Some improvements using PROJECT_IS_TOP_LEVEL variable ...

71f746c057 cmake: Include `include` directory for subtree builds (Hennadii Stepanov)
5431b9decd cmake: Make `SECP256K1_INSTALL` default depend on `PROJECT_IS_TOP_LEVEL` (Hennadii Stepanov)
162608cc98 cmake: Emulate `PROJECT_IS_TOP_LEVEL` for CMake<3.21 (Hennadii Stepanov)

Pull request description:

  This PR:
  1. Emulates [`PROJECT_IS_TOP_LEVEL`](https://cmake.org/cmake/help/latest/variable/PROJECT_IS_TOP_LEVEL.html) variable for CMake versions where it is not available.
  2. Makes the `SECP256K1_INSTALL` option dependent on `PROJECT_IS_TOP_LEVEL` (a [follow up](https://github.com/bitcoin-core/secp256k1/pull/1263#issuecomment-1516564300) of https://github.com/bitcoin-core/secp256k1/pull/1263).
  3. Makes integration of this project as a subtree easier. A top project can `#include <secp256k1.h>` with no additional `target_include_directories()` commands. For example, see https://github.com/hebasto/secp256k1-CMake-example/tree/subtree.
