Bug 1865324 [wpt PR 43228] - compute pressure: Try to exit earlier in…

… the rate obfuscation web test, a=testonly

Automatic update from web-platform-tests
compute pressure: Try to exit earlier in the rate obfuscation web test

This test is known to be long and apparently times out
on some Mac bots.

This patch is reducing the test execution time by exiting
as soon as the test pass condition is met.

The sampling frequency has been increased to shorten
execution time.
