Remove patches/chrome-browser-profiles-profile_io_data.cc.patch

[mariospr]

Description

The idea of this patch is simply to make sure that the brave:// scheme gets considered by ProfileIOData::IsHandledProtocol() along with other schemes, but we can achieve the same goal just using chromium_src overrides, so let's do that instead.

Desktop Brave version:

Brave 1.22.28 (Chromium 89.0.4389.48)

Miscellaneous Information:

For QA purposes: this cleanup touched code added to fix bugs #2861 and #2849, so please make sure behaviour remains the same.

There is a test plan in the associated PR in brave/brave-core#1196

Verified FIXED using the testplan from brave/brave-core#1196 with

Brave	1.22.51 Chromium: 89.0.4389.72 (Official Build) beta (x86_64)
Revision	3f345f156bfd157bd1bea06310e55f3fb2490359-refs/branch-heads/4389@{#1393}
OS	macOS Version 11.2.2 (Build 20D80)

Test 1:
Navigate to https://world_languages.gitlab.io/bravepoc/
Click link
Check brave://settings is not loaded in new tab.

Confirmed that example.com opened in a new tab, instead

Test 2:

Navigate to brave://welcome
Move to Change your search engine page in welcome page
Click Settings button
Check settings page is opened in new tab

The above testcase was for previous UI; I instead used the 3rd page in brave://welcome, which has Settings linked, as shown here.

Verified that it opened chrome://settings/privacy in a new tab.

Step 1	Step 2

Test 3:

Open brave://settings
Right click on `brave://sync
Check Save Link As... is disabled

I confirmed via #brave-core in Slack that this is also outdated UI; @simonhong confirmed that the new test is actually to make sure that Save Link As... is enabled for a corresponding chrome:// link.

Verified that right-clicking and choosing Save Link As... for chrome://settings/braveSync resulted in the following dialog.

Step 1	Step 2
