* Revert "Update gradle wrapper and build-tools version for flutter create. (#8914)"
This reverts commit deb71cc6dcf45297ab4fb6e6ccf3d14fb05be9ab.
The old `whichAll` implementation was not considering different extensions for executables on Windows. By defering to OS-built-in tools we avoid implementing it.
Fixes#8882.
* Update gradle wrapper and build-tools version.
Tested manually by "flutter create" with Idea "flutter run" and from android studio "run" android app.
* Update com.android.tools.build to 2.3.0
Previously they tried to compute an integer target end index, but
integers can't represent infinity. Now we use null to represent
infinity.
Also, fix some similar issues with grids.
Fixes#8398
* Remove legacy .apk build.
Print out an error message telling the user to upgrade the project if
it's not Gradle-based. Removed all the obvious traces of the legacy
build.
Added support for Dart VM kernel snapshots in Gradle builds.
Fixed Android installs to verify that the app is actually installed, and
not just rely on the presence of the .sha1 file.
The recommended minimum tappable area is actually 44.0pt according to the [iOS Human Interface Guidline](https://developer.apple.com/ios/human-interface-guidelines/visual-design/layout/).
> Provide ample spacing for interactive elements. Try to maintain a minimum tappable area of 44pt x 44pt for all controls.
I've also added an override to allow for flexibility in situations where designers get naughty and have a desire to make everything super small.
This update adds support for custom fonts in icons. As an example, it
can be used with the icon-set from https://materialdesignicons.com
Thanks to @vlidholt for the original patch.

Breaking change: removed deprecated methods of PlatformMessages, leaving only binary messaging there. All other use of platform communication now goes through PlatformMessageChannel and PlatformMethodChannels. Retained use of String and JSON codecs for now.
