Oriol Catalan d936372eab lib: sbi: Make per-HART stack size configurable via Kconfig ...

The per-HART stack size for exception/interrupt handling is currently
hardcoded to 8192 bytes in SBI_PLATFORM_DEFAULT_HART_STACK_SIZE. This
may not be sufficient for platforms with deeper call stacks (e.g. those
enabling additional SBI extensions) or may be wasteful for minimal
platforms.

Introduce a HART_STACK_SIZE Kconfig option in lib/sbi/Kconfig with a
valid range of 8192 to 1048576 bytes and a default of 8192 bytes to
preserve existing behavior. The SBI_PLATFORM_DEFAULT_HART_STACK_SIZE
macro now resolves to CONFIG_HART_STACK_SIZE, allowing all platforms
to benefit from a single configuration knob without any source changes.
