Newer GCC emits C++ global constructors into .init_array, which many
linker scripts keep outside [__ctors_start__, __ctors_end__), so they
never ran. Walk __init_array_start/__init_array_end (weak) as well,
skipping entries already covered by the ctors range.
Add RT_USING_CPP_CRT_INIT for ports whose startup runtime already runs
.init_array, default on for the simulator. With it set, only the
.init_array walk is skipped; the ctors range is still walked.
Renesas RA/RA_WIRELESS/RZ families select it when C++ is enabled: FSP
SystemInit() already walks .init_array, so boards whose linker script
only provides __init_array_* would run constructors twice. Boards that
fold .init_array into the ctors range (ra6m3-hmi-board, ra8d1, rz)
still run them once via RT-Thread.
Also source env.sh and restore RTT_EXEC_PATH in ToolsCI project generate
and dist steps so scons is on PATH (exit 127) and the ARM toolchain path
is not overwritten by env.sh.
Fixes #11778

Use "Test" instead of "Unit Testcases" to make string shorter.
Use uppercase to make it look more eye-catching.

Also update the case names to compatible with naming rules.

* [rtdef] rename RT_WEAK attribute as rt_weak
* [rtdef] rename RT_USED attribute as rt_used
* [rtdef] rename RT_SECTION attribute as rt_section
* [rtdef] rename ALIGN attribute as rt_align
* [legacy] add RT_USED ALIGN RT_SECTION RT_WEAK as legacy support
