Add a header_abi_checker section

This commit adds a header_abi_checker section so that the library owner
can have a fine-grained control over the ABIs that must be checked.

For example, a library "libexample" may have following configurations:

    cc_library {
        name: "libexample",
        header_abi_checker: {
            symbol_file: "libexample.map.txt",
            exclude_symbol_versions: ["LIBEXAMPLE_PRIVATE"],
            exclude_symbol_tags: ["platform", "apex"],
        },
    }

Bug: 122845490
Test: Add header_abi_checker to libc to filter out LIBC_PRIVATE
