Add a tracing API and instrument key functions in order to profile
aapt2 bottleneck. The API allows to generate systrace fragment files.
Impact on performance is neglibible with each Trace requiring less
than 1us and the final Flush operation at the end of a command
requiring around 40us.

Compiled Strings (previously not encountered) in an XML resource
were using a different StringPool than the one being referred to
in the XmlFlattener, and so the indices were all wrong.

We assumed that a raw text value set for an attribute meant there
were no compiled values set either.
This would only really happen for attributes that did not belong to any
namespace (no prefix:), since we always kept their raw string values
in case some code relied on it.

This change injects the 'android:compileSdkVersion' and
'android:compileSdkVersionCodename' into an app's AndroidManifest.xml,
whose values are dervied from the version name and version code of the
framework AndroidManifest.xml that is being linked against.

(generated from the link phase using --proto-format) into
a binary APK suitable for use on device.

AAPT Container Format (.apc) is a simple container that
enumerates the various intermediate files that AAPT2 generates
during the compile phase.
The format is defined in formats.md.
For now, continue using the .flat extension for the container file,
and keep making use of the .flata zip for storing multiple files.
This will allow easier integration with existing build systems and allow
the evolution of the APC format to better handle arbitrarily large
files.

* Added the resource ID pulled from the XML parser into the compiled
attribattribue. This allows binary attributes such as the version code
and min SDK values to be available whern flattening the XmlResource back
into an APK file.
* Only add a compiled value if the attribute value was not a string.
This allows string values like the package name and version name to be
flattened back into an APK file.
Before making this change, aapt would segfault when dumping the manifest
and dumping badging would be missing values. After making this change,
the manifest and badging are dumping correctly.

In preparation for exporting an XML proto format for UAM to consume,
this change brings the XML DOM API more in line with other APIs that
do not make the Namespace a separate node.
Treating Namespace declarations as just properties of an Element
node makes the implementation of algorithms much simpler, as
the constraints that Namespace nodes have only one child
are now built in and traversing to find Element nodes
is much simpler.
Also made a bunch of quality of life improvements, like formatting and
comment style.

Mingw64 was being difficult, so instead of defining a wmain entrypoint,
the command line parameters are parsed manually using built-in Windows
methods that support Unicode. The results are converted to UTF8 and
handled just like the rest of the linux/mac version of the code.
This also removes dependencies on std::istream in favour of a
FileInputStream which calls the appropriate unicode version of
open to read a file.
No speed regressions found on Linux or MacOS.

This change defines some hardcoded rules to degrade
attributes in newer SDKs to specific older attributes.
An attribute with a degrade rule will generate a new XML for the API
in which the attribute resulting from the degradation was introduced.
Since API 22 (Lollipop MR1), attributes are correctly ignored and do
not need to be versioned. In XML files defined for APIs 22+, the
original and degraded attributes coexist in the same XML file.
One such example is paddingHorizontal, introduced in API 26.
paddingHorizontal degrades to paddingLeft and paddingRight, which
were both introduced in API 1.

Generating splits should be possible to do from the optimize command.
This means that a lot of infrastructure around split APKs can be
shared by both the optimize and link phase.

Use Google3 naming style to match new
projects' and open source google projects' style.
Preferred to do this in a massive CL so as to avoid
style inconsistencies that plague legacy code bases.
This is a relatively NEW code base, may as well keep
it up to date.

For legacy reasons, we kept around the use of UTF-16 internally
in AAPT2. We don't need this and this CL removes all instances of
std::u16string and StringPiece16. The only places still needed
are when interacting with the ResTable APIs that only operate in
UTF16.
