acpigen: Add printf-like function for debug string

Generate formatted string and ACPI code to print debug string.

For example (with pcie_rp = 1):

    acpigen_write_debug_sprintf("calling _ON for RP: %u", pcie_rp);

generates the following ACPI code:

    Debug = "calling _ON for RP: 1"

With this new function, the following functions are not needed anymore
and therefore are removed by this patch.

- acpigen_concatenate_string_string()
- acpigen_concatenate_string_int()
- acpigen_write_debug_concatenate_string_string()
- acpigen_write_debug_concatenate_string_int()

BRANCH=firmware-brya-14505.B
TEST=Add above functions in the acpigen code and check the generated
     SSDT table after OS boot. Check the debug messages is in the
     kernel log when /sys/modules/acpi/parameters/aml_debug_output is
     set to '1'.
