Introduced `CONFIG_PLIC_SHELL` to enable the build of shell
debugging command to get the hit count of each interrupt
controller's IRQ line. This is especially useful when working
with dynamically installed ISRs, which will be the case for
`plic_sw`.
Example usage:
```
uart:~$ plic stats get interrupt-controller@c000000
IRQ Hits
==================
10 177
uart:~$ plic stats get interrupt-controller@c000000
IRQ Hits
==================
10 236
uart:~$ plic stats clear interrupt-controller@c000000
Cleared stats of interrupt-controller@c000000.
uart:~$ plic stats get interrupt-controller@c000000
IRQ Hits
==================
10 90

Removing the edge-trigger Kconfig as it is supported by default
in the RISCV PLIC specifications.
Define the edge-trigger register offset in the driver instead
of retrieving the value from devicetree as it is not something
configurable. The value 0x1080 is defined in Andes & Telink
datasheets.
Updated build_all testcase.

Update intc drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

Introduce a new RISCV_HAS_CLIC symbol for platforms using CLIC,
reorganize the Kconfigs and make the Nuclei ECLIC depending on the new
symbol.
