Subject: [PATCH] DO NOT MERGE Ignore - Sanitized uri scheme by removing scheme
 delimiter

Initially considered removing unsupported characters as per IANA guidelines, but this could break applications that use custom schemes with asterisks. Instead, opted to remove only the "://" to minimize disruption

Bug: 261721900
Test: atest FrameworksCoreTests:android.net.UriTest

No-Typo-Check: The unit test is specifically written to test few cases, string "http://https://" is not a typo

NOTE FOR REVIEWERS - original patch and result patch are not identical.
PLEASE REVIEW CAREFULLY.
