This renames a few RV32 configs to follow the convention that names w/o
numbers are for RV32, so that to be in line with majority RV32 configs.
As a result, we have: `nsh` vs `nsh64`, `knsh` vs `knsh64`, `pnsh`
vs `pnsh64`,`flats` vs `flats64`, `nsbi` vs `nsbi64`, `libcxx` vs
`libcxx64` etc. This helps us pick the right config name w/o checking
file contents.

This PR adds a new Build Config `rv-virt:leds64_rust` that builds the Rust App `leds_rust` for QEMU RISC-V 64-bit. The build requires the [Rust Target `riscv64gc-unknown-none-elf`](https://github.com/apache/nuttx/pull/12858):
```bash
rustup target add riscv64gc-unknown-none-elf
```
New Files:
`boards/risc-v/qemu-rv/rv-virt/configs/leds64_rust/defconfig`: Add new Build Config `rv-virt:leds64_rust`
Updated Docs:
`applications/examples/leds_rust/index.rst`: Add `leds_rust` example app
`platforms/risc-v/qemu-rv/boards/rv-virt/index.rst`: Add `rv-virt:leds64_rust` config
This revises PROTECTED build for qemu-rv mainly to avoid hard-coded
addresses in linker scripts. It also added rv32 support, cleaned up
config `pnsh64` and added config `pnsh`.

This adds NuttSBI support for rv-virt device so that to enable CI
checks for NuttSBI later. It allows using `-bios nuttx` option to
run NuttX with QEMU v6.2 w/o OpenSBI.

- This PR adds the LED Driver for QEMU RISC-V 32-bit and 64-bit (User LEDs and Auto LEDs)
- QEMU RISC-V LED Driver will be used by the Rust Blinky App for Google Summer of Code
- Blinking the LED is probably the most common Embedded Demo, and now it's supported by QEMU RISC-V
- We added NuttX Configs `rv-virt:leds` and `rv-virt:leds64` to support User LEDs for 32-bit and 64-bit RISC-V
- Turning on/off a Simulated User LED will print a log message: "LED 1 set to 1"
- The code is derived from NuttX PinePhone LED Driver
This patch can boot `rv-virt/knsh64` and `rv-virt/knsh32` reported in
issue #12275 with qemu 6.2 target and OpenSBI v1.0 firmware on Ubuntu
22.04 host.

The qemu-rv use a small init code for M mode in kernel build.
It is hard-coding and is difficult to change. Due to the fact,
introduce a already mature SBI implement (e.g OpenSBI) to
replace existing code is a better choice.
This patch introduce some change for qemu-rv:
1. use SSTC to provide time interrupt in kernel build
2. remove uncessary M mode trap.
For simplicity, this patch does not add support for booting
nuttx for any core, but force boot core to start core 0 and
let core 0 do the initialization.

When an application is being loaded `up_addrenv_create ` calls
`create_region` to create the address environment. Only the first
entry is mapped when the region is created. Virtual memory that is
not mapped will trigger an exception when accessed. Other memory
pages are allocated and mapped on-demand. This enables setting
larger heap and stack for the process without compromising the
overall system memory.

Fully linked apps take less storage and are efficient to load. This
is to enable them for rv-vrit configurations in KERNEL build.
Changes:
- arch/risc-v/Kconfig select BINFMT_ELF_EXECUTABLE for QEMU-RV
- boards/risc-v/qemu-rv/rv-virt/configs
- knsh32/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- knsh64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- ksmp64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- knetnsh64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
- knetnsh64_smp/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST
Additions:
- boards/risc-v/qemu-rv/rv-virt/scripts/
- gnu-elf.ld apps linker script
The ARCH_TEXT_VBASE of knsh32 is set to same as that of 64bit to reuse

This provides the initial hooks for Flattened Device Tree support
with QEMU RV. It also provides a new procfs file that exposes the
fdt to userspace much like the /sys/firmware/fdt endpoint in Linux.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw
Nodes in the fdt are not yet usable by the OS.
