arch: remove CONFIG_LEGACY_MULTI_LEVEL_TABLE_GENERATION

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

(cherry picked from commit 588ccd9)
