Convert node test compile-time settings into run-time parameters

This converts

    COPY_PARSE_PLAN_TREES
    WRITE_READ_PARSE_PLAN_TREES
    RAW_EXPRESSION_COVERAGE_TEST

into run-time parameters

    debug_copy_parse_plan_trees
    debug_write_read_parse_plan_trees
    debug_raw_expression_coverage_test

They can be activated for tests using PG_TEST_INITDB_EXTRA_OPTS.

The compile-time symbols are kept for build farm compatibility, but
they now just determine the default value of the run-time settings.

Furthermore, support for these settings is not compiled in at all
unless assertions are enabled, or the new symbol
DEBUG_NODE_TESTS_ENABLED is defined at compile time, or any of the
legacy compile-time setting symbols are defined.  So there is no
run-time overhead in production builds.  (This is similar to the
handling of DISCARD_CACHES_ENABLED.)
