- Edited linker script for shmem to have condition according to cores selected.
- Added new configuration for nsh_cm7_rptun and nsh_cm4_rptun.
- Appended RPTUN bringup code in stm32_bringup.c

reason:
1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

Basic amg88xx sensor handling (open, close, read, ioctl).
No interrupts supported. I intend to add support for this feature when I
gain more know-how on nuttx/posix.
Make this_cpu is arch independent and up_cpu_index do that.
In AMP mode, up_cpu_index() may return the index of the physical core.

Some domains have a lot of IPv6 addresses. Because of that, it is
not possible to get the IPv4 address with getaddrinfo.
This change separate IPv4 and IPv6 cache size limit to enable to
get both IP addresses.
After the number of threads exceeds the array size, it will not be displayed.
Any number of threads can be displayed using dynamic adaptation

Prior to this commit, i2c and at24 may be used uninitialized on line
113, 117, 129, and 143 when gd32_at24_wr_test() is called the second
time because these two variables are not static. I don't think making
them static is the correct fix because i2c is released at the end of
this function. Fixed by removing the `if (!initialized)` condition
surrounding the initialization of i2c and at24, making them initialized
at every call to this function.

Description:
Example to interact with KEY button and user external button connected to PA1.
For KEY button pull-up resistor is active, board schematic does not show any pull-up or pull-down resistor.
Results: Example working as expected.

(1) Keep the `.init_array` and `.ctors` symbols and sort them according to their initialization priority.
(2) Exclude symbols ending with crtend.* and crtbegin.* to support c++
application.if we not exclude crtend.* crtbegin.* frame_dummy will be
added when enable any c++ application with global variables, this symbol
execution is problematic, removing it does not affect the application.

This reverts both 2afdcfb6a6 and 0a0af89de9 to restore the 128K kflash
design as the implementation depends on that to work, checked with:
```
$ qemu-system-arm -M lm3s6965evb -nographic -device \
