lib: crc32: put the crc_table variable into efi_runtime_rodata section
When compiling with LTO, the compiler fails with an error saying that `crc_table` causes a section type conflict with `efi_var_buf`. This is because both are declared to be in the same section (via macro `__efi_runtime_data`), but one is const while the other is not. Put this variable into the section .rodata.efi_runtime, instead of .data.efi_runtime, via macro __efi_runtime_rodata.
