MDL-46812 grade/report/grader: Need to tie up loose ends in Gradebook after MDL-43824
1. fixed gradebook layout when JS is disabled
2. added height and background color to scroller when JS is enabled
3. removed redundent top margin in user-grades table
This makes the strings more descriptive and consistent.

The grader report table makes use of various user preferences, and strings
which on every iteration. On a large gradebook, this can have a significant
impact upon performance.
The table also uses html_writer::tag to generate spans for
machine-generated content which becomes expensive on larger gradebooks.
The code only needs the id column to perform its count. On courses with a lot of users
fetching the whole user record for them all easily adds up to several hundred MB of
memory.
Changes core code to use new API instead of the old one when
checking user access to activities and sections.
Includes changes to other libraries that are necessary after
adding the availability system and removing old conditional tables
etc.
* core_useragent: Introduce is_vendor methods to improve readability
when we are just detecting if a browser is from a vendor, rather than
the exact version
* Remove uncessary browser version checks when we are just detecting
vendors - this makes the intention of our sniffing clearer.
* Remove sniffing for browsers which we do not support, grades/ajax/tinymce
all support modern browsers so there is no need to sniff for them.
