remove panel action FTR tests (elastic#273345)

Part of elastic#271763

src/platform/test/plugin_functional/test_suites/panel_actions test that
actions registered to trigger `ON_OPEN_PANEL_MENU` are displayed in
panel context menu. This is better tested at the unit level and already
covered at the integration level. Most dashboard tests already test
specific context menu actions so a test is not needed to verify actions
registed to trigger `ON_OPEN_PANEL_MENU` are displayed in panel context
menu.

PR also removes kbn_sample_panel_action plugin since it was only used by
this FTR test.
