a9372627d8 risc-v/rv-virt: use fully linked apps for kernel build 
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
the apps linker script.

10ef3900b2 risc-v/qemu-rv: Mark the page table section as NOLOAD 
Otherwise the linker will allocate an output section for it, which actually
uses kernel ROM memory for nothing

8defb843aa Remove duplicate linker script definitions 
## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.

This PR cleans up the logic so they're only listed once.

 ## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!

 ## Testing
CI will test all build
