Add semihosting support for Xtensa architecture.
Existing semihosting instructions are based on ARM, so they are
converted to Xtensa codes before the semihosting call is invoked.
Return codes of read, write and seek calls had to be converted to match
semihosting API definitions.

`CONFIG_LEGACY_MULTI_LEVEL_TABLE_GENERATION` had been deprecated since
#66877 for 2 releases, interrupt controller drivers should have been
updated to use the new `IRQ_PARENT_ENTRY_DEFINE()` macro. Remove it.

Previously, there were two separate Kconfig definitions
of ARM_MPU located at:
- arch/arm/core/mpu/Kconfig
- arch/arm64/core/cortex_r/Kconfig
This lead to incomplete default settings and unexpected
missing configurations.
This commit combines the two into a single unified definition
now located at arch/common/Kconfig to prevent this.

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.

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.
