Replace --sdk-extension-root with --android-jar-pattern

Previously, the only way to specify the location of the SDK extension
jars was to specify the `--sdk-extension-root` directory and then rely
on Metalava's hard-coded pattern to find the jar files. However, it is
now possible to specify the SDK extension jar pattern explicitly as an
`--android-jar-pattern` option.

This change makes use of that new capability to specify patterns for
the SDK extension jars appropriate for the API surface being generated
and removes the `--sdk-extension-root` option altogether.
