src/acpi: add debug message with concatenated string

add functions for concatenate OP
add debug message containing concatenated string with string, value, or
OPs

Ex1: to print string with another string provided from C side:
acpigen_write_debug_concatenate_string_string("Wait loop Timeout! var=",
            name, LOCAL6_OP);
will generate:
    Concatenate ("Wait loop Timeout! var=", "L23E", Local6)
    Debug = Local6

Ex2: to print string with a value:
acpigen_write_debug_concatenate_string_int("ModPHY enabling for RP:",
    pcie_rp, LOCAL0_OP);

will generate:
    Concatenate ("ModPHY enabling for RP:", 0x05, Local0)
    Debug = Local0

Ex3: to print string with an ACPI OP:
acpigen_write_debug_concatenate_string_op("while Loop count: ",
    LOCAL7_OP, LOCAL6_OP)

will generate:
    Concatenate ("while Loop count: ", Local7, Local6)
    Debug = Local6

TEST=Add above functions in the acpigen code and check the generated
SSDT table after OS boot
