Enable optimize max for GN builds + update docs 

Optimize max enables O2 for official builds.  Normally release builds
are O2 but the official build is Os, affecting performance.
The GYP file was previously updated to enable optimize max,
which enables ltcg and O2.

Documentation updated to show GN builds in docs/getting_started.md

# Deprecated Builds
Older documentation on build configs which are no longer supported.
## Pre-requisites
You'll need to have depot tools installed: https://www.chromium.org/developers/how-tos/install-depot-tools
Refer to chromium instructions for each platform for other prerequisites.
## Getting the Code
Create a working directory, enter it, and run:
gclient config https://chromium.googlesource.com/libyuv/libyuv
gclient sync
Then you'll get a .gclient file like:
solutions = [
{ "name" : "libyuv",
"url" : "https://chromium.googlesource.com/libyuv/libyuv",
"deps_file" : "DEPS",
"managed" : True,
"custom_deps" : {
},
"safesync_url": "",
},
];
For iOS add `;target_os=['ios'];` to your OSX .gclient and run `GYP_DEFINES="OS=ios" gclient sync.`
Browse the Git reprository: https://chromium.googlesource.com/libyuv/libyuv/+/master
### Android
For Android add `;target_os=['android'];` to your Linux .gclient
solutions = [
{ "name" : "libyuv",
"url" : "https://chromium.googlesource.com/libyuv/libyuv",
"deps_file" : "DEPS",
"managed" : True,
"custom_deps" : {
},
"safesync_url": "",
},
];
target_os = ["android", "unix"];
Then run:
export GYP_DEFINES="OS=android"
gclient sync
Caveat: Theres an error with Google Play services updates. If you get the error "Your version of the Google Play services library is not up to date", run the following:
cd chromium/src
./build/android/play_services/update.py download
cd ../..
For Windows the gclient sync must be done from an Administrator command prompt.
The sync will generate native build files for your environment using gyp (Windows: Visual Studio, OSX: XCode, Linux: make). This generation can also be forced manually: `gclient runhooks`
To get just the source (not buildable):
git clone https://chromium.googlesource.com/libyuv/libyuv

### Running Valgrind memcheck
Memory errors and race conditions can be found by running tests under special memory tools. [Valgrind] [1] is an instrumentation framework for building dynamic analysis tools. Various tests and profilers are built upon it to find memory handling errors and memory leaks, for instance.
