support query encoding in http, http, ftp and fix path decode issues

[jrieken]

This PR is for #25852 and #45515

[jrieken]

@isidorn these changes make some tests in debug land fail:

vscode/src/vs/workbench/contrib/debug/test/electron-browser/debugModel.test.ts

Line 393 in c653508

assert.equal(firstStackFrame.getSpecificSourceName(), '.../b/c/d/internalModule.js');

It seems like the debug source is build on the (bug) behaviour described in #45515, e.g when the path component contains an encoded / (%2f) it should not be decoded but kept as is

[isidorn]

Looking at it I am not sure why do we encode the path component here

@weinand introduced the encoding of the uri for the debug source so he would be better to comment here.

[jrieken]

If the goal is to create new uris from existing components, than you should use URI.from

[isidorn]

Yeah that seems like the way to go.
I can do the changes if @weinand agrees

[weinand]

@isidorn yes, please adapt.

[jrieken]

Great - let me know if you need help

[isidorn]
