hv:Replace dynamic memory with static for port io

-- Add emulated port io index
-- Add emulated pio array in vm structure
-- Remove port list in vm structure
-- Remove free_io_emulation_resource/register_io_handler/
   create_io_handler APIs

v2-->v3:
 -- not add 'is_emulated', check len == 0U
 -- Check if io_read/io_write handler is NULL before calling
 -- Replace ENUM with MACRO for emulated pio index to avoid
    MISRA-C violations

v1-->v2:
  -- Remove EMUL_PIO_NUM in Kconfig, add emulated pio index
     for PIC/PCI/UART/RTC/PM
