[pg15] test: re-port regress misc, misc_functions, prepare

Summary:
Re-port pg_regress tests misc, misc_functions, and prepare.  These tests
originally exist in yb_pg_misc_independent_serial_schedule, but since
they now rely on test_setup, move them to yb_pg_misc_serial_schedule.

Test Plan:
On Almalinux 8:

    #!/usr/bin/env bash
    set -eu
    ./yb_build.sh fastdebug --gcc11
    yes "$(grep TestPgRegressPgMisc pg15_tests/passing_tests.tsv)" | head -50 | pg15_tests/run_tests.sh

Jenkins: rebase: pg15, test regex: TestPgRegressPgMisc
