Chris Bracken 4fd686f454 Document rationale for Dart VM flag prefix match (flutter/engine#30195) ...

Dart VM flags are passed to Flutter via an fml::CommandLine::Option that
looks something like:

   {"dart-flags, "--max_profile_depth 1,--trace_service"}

We perform a prefix match to handle cases where Dart VM options take
arguments.

Adding the comment since in a recent review I found myself wondering why
we're using a prefix match to begin with. While the original author had
forgotten, the good news is, he wrote a test that covers this exact
case. This comment just removes one level of indirection for future
readers.
