Erick Reyes 2f6792e286 libmeminfo: make libdmabufinfo and dmabuf_dump vendor available
Removed dependency on libc++fs and changed liblog to shared linkage to
cope with build errors derived from the change.

Removed dmabuf_dump unnecessary dependencies and made it soc_specific.

Removed reference to std::filesystem::is_symlink to workaround the
following error when linking with the library:

ld.lld: error: undefined symbol:
std::__1::__fs::filesystem::__symlink_status(std::__1::__fs::filesystem::path
const&, std::__1::error_code*)
>>> referenced by filesystem:1743
(external/libcxx/include/filesystem:1743)
>>>
dmabufinfo.o:(android::dmabufinfo::AppendDmaBufInfo(int,
std::__1::vector<android::dmabufinfo::DmaBuffer,
std::__1::allocator<android::dmabufinfo::DmaBuffer> >*)) in archive

Erick Reyes d2918fe218 meminfo: Add memtrack dmabufinfo library
This is the userspace component for the improved shared memory buffer
tracking.

A new static library called libdmabufinfo will provide APIs to parse dmabuf
debugfs entries. The library can also map and read the file descriptors
per process to cross-reference the global data per process.

This change only adds a global API to read dmabuf stats from debugfs.

Test: dmabufinfo_test
