arch: common: dedicated `SEMIHOST` symbol Control the usage of semihosting with a dedicated symbol, instead of implying semihosting from the usage of `SEMIHOST_CONSOLE`. This allows semihosting to be used without the semihost console. Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au>

config SEMIHOST
bool "Semihosting support for ARM and RISC-V targets"
depends on ARM || ARM64 || RISCV
help
Semihosting is a mechanism that enables code running on an ARM or
RISC-V target to communicate and use the Input/Output facilities on
a host computer that is running a debugger.
Additional information can be found in:
https://developer.arm.com/documentation/dui0471/m/what-is-semihosting-
https://github.com/riscv/riscv-semihosting-spec/blob/main/riscv-semihosting-spec.adoc
This option is compatible with hardware and with QEMU, through the
(automatic) use of the -semihosting-config switch when invoking it.
arch: sw_isr: revamp multi-level interrupt architecture Previously the multi-level irq lookup table is generated by looping through the devicetree nodes using macros & Kconfig, which is hard to read and flimsy. This PR shifts the heavy lifting to devicetree & DT macros such that an interrupt controller driver, which has its info in the devicetree, can register itself directly with the multi-level interrupt architecture, which is more straightforward. The previous auto-generated look up table with macros is now moved in a file of its own. A new compatibility Kconfig: `CONFIG_LEGACY_MULTI_LEVEL_TABLE_GENERATION` is added and enabled by default to compile the legacy look up table for interrupt controller drivers that aren't updated to support the new architecture yet.

with the legacy way using DT macros.
