Merge #18514: test: remove rapidcheck integration and tests

9e071b00898aedd9632f105a22d976dc6dbc84b1 test: remove rapidcheck integration and tests (fanquake)

Pull request description:

  Whilst the property tests are interesting, ultimately [rapidcheck](https://github.com/emil-e/rapidcheck) integration in this repository has not gained much traction. We have a limited number of tests, and they are rarely (if ever) run. Have discussed this with Chris Stewart.

-# RapidCheck property-based testing for Bitcoin Core
-
-## Concept
-
-Property-based testing is experimentally being added to Bitcoin Core with
-[RapidCheck](https://github.com/emil-e/rapidcheck), a C++ framework for
-property-based testing inspired by the Haskell library
-[QuickCheck](https://hackage.haskell.org/package/QuickCheck).
-
-RapidCheck performs random testing of program properties. A specification of the
-program is given in the form of properties which functions should satisfy, and
-RapidCheck tests that the properties hold in a large number of randomly
-generated cases.
-
-If an exception is found, RapidCheck tries to find the smallest case, for some
-definition of smallest, for which the property is still false and displays it as
-a counter-example. For example, if the input is an integer, RapidCheck tries to
-find the smallest integer for which the property is false.
-
-## Running
-
-If RapidCheck is installed, Bitcoin Core will automatically run the
-property-based tests with the unit tests during `make check`, unless the
-`--without-rapidcheck` flag is passed when configuring.
-
-For more information, run `./configure --help` and see `--with-rapidcheck` under
-Optional Packages.
-
-## Setup
-
-The following instructions have been tested with Linux Debian and macOS.
-
-1. Clone the RapidCheck source code and cd into the repository.
-
-    ```shell
-    git clone https://github.com/emil-e/rapidcheck.git
-    cd rapidcheck
-    ```
-
-2. Build RapidCheck (requires CMake to be installed).
-
-    ```shell
-    cmake -DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=true -DRC_ENABLE_BOOST_TEST=ON $(pwd)
-    make && make install
-    ```
-
-3. Configure Bitcoin Core with RapidCheck.
-
-    `cd` to the directory of your local bitcoin repository and run
-    `./configure`. In the output you should see:
-
-    ```shell
-    checking rapidcheck.h usability... yes
-    checking rapidcheck.h presence... yes
-    checking for rapidcheck.h... yes
-    [...]
-    Options used to compile and link:
-    [...]
-      with test     = yes
-        with prop   = yes
-    ```
-
-4. Build Bitcoin Core with RapidCheck.
-
-    Now you can run `make` and should see the property-based tests compiled with
-    the unit tests:
-
-    ```shell
-    Making all in src
-    [...]
-    CXX      test/gen/test_bitcoin-crypto_gen.o
-    CXX      test/test_bitcoin-key_properties.o
-    ```
-
-5. Run the unit tests with `make check`. The property-based tests will be run
-   with the unit tests.
-
-    ```shell
-    Running tests: crypto_tests from test/crypto_tests.cpp
-    [...]
-    Running tests: key_properties from test/key_properties.cpp
-    ```
-
-That's it! You are now running property-based tests in Bitcoin Core.
