Bug 1614612 [wpt PR 21728] - Update performance.measureMemory to the latest proposal, a=testonly

Automatic update from web-platform-tests
Update performance.measureMemory to the latest proposal (#21728)

* Update performance.measureMemory to the latest proposal

This changes the result format of the API to the latest version of
the proposal at https://github.com/ulan/performance-measure-memory.
Specifically, the result format changes from JS only and per-frame:
{
  total: {
    jsMemoryEstimate: 200*MB,
    jsMemoryRange: [100*MB, 300*MB]
  },
  current: {..},
  other: [..]
}

to more a generic format with breakdown:
{
  bytes: 70*MB,
  breakdown: [
    {bytes: 40*MB, globals: 2, type: 'js', origins: ['foo.com']},
    {bytes: 30*MB, globals: 1, type: 'js', origins: ['bar.com']}
  ]
}

Additionally this patch skips extension contexts and relaxes
cross-origin memory measurement for site-isolated pages.
