Merge #17542: build: Create test utility library from src/test/util/

a2e581de94 build: Create test utility library from src/test/util/ (Harris)

Pull request description:

  This PR creates a static **test utility library** that replaces repetitive compilations of sources from *src/test/util* in **unit**, **gui** and **bench** **tests**.

  The original issue is here: https://github.com/bitcoin/bitcoin/issues/17401

  The changes are:

  * a new *Makefile.test_util.include*
  * a new entry in *Makefile.am* that includes *Makefile.test_util.include* when testing is enabled
  * removal of all *src/test/util* headers & sources from unit, gui and bench Makefiles
  * addition of *libtest_util.a* at LDADD's of every test
