Create bp2build converter for versioned_ndk_headers
This module type is used by a single soong module - `common_libc` in
bionic/libc
Implementation details
- Convert this module type to ndk_headers rule. Bazel's ndk_headers rule
will have a boolean attribute `run_versioner` to determine if
verioner should be run on the headers
- Add this module type to the alwaysConvert bp2build list
- Add the converted target for `common_libc` to the deps of
`ndk_sysroot`. This ensures that unbundled apps link against the
versioned NDK headers of libc
Test: go test ./bp2build
Test: b build //bionic/libc:common_libc --config=android
Test: for f in $(find bazel-bin/bionic/libc/common_libc.versioned -type f); do cmp $f ${f/bazel-bin\/bionic\/libc\/common_libc.versioned/out\/soong\/ndk\/sysroot\/usr\/include}; done # no diff
