1773997 - Add tests for loading import maps with <base> element

Status: RESOLVED FIXED

(Core :: JavaScript Engine, task, P3)

Description

[Yoshi Cheng-Hao Huang [:allstars.chh][:allstarschh][:yoshi]]

See https://github.com/WICG/import-maps#base-element
If there's a <base> element, it will change the base URI of the document, which will also change the baseURL in import maps.
So we should have some tests to make sure import maps behaves correctly with the <base> element.
Also, the test could be used to test the speculative parsing of import maps in Bug 1762595

Attachment: Bug 1773997 - Part 2: Use absolute path when calling static_import.py

With the <base> element, the relative path will be changed, therefore
modifying the script.src to use absolute paths if it's using relative path.

Attachment: Bug 1773997 - Part 3: wpt with <base> for import-maps.

With <base> element changes the base URL to "./resources/", the baseURL
of the import map should be updated as well.
The url "log.js" in the import map will be resolved to "./resources/log.js".

Attachment: Bug 1773997 - Part 4: wpt for injecting a <base> element for import-maps.

Add a helper function called testInIframeInjectBase, which will include
a Javascript file, which will in turn inject a <base> element into current
document.
