docs(per-cpu): clean up NUMA docs

This change incorporates resolutions for the remaining code review
comments on the NUMA documentation, which were intentionally left
unresolved when the NUMA stack was expedited.

Additionally, general improvements include:

- Documentation has been re-flowed with Pandoc;
- Diagram file-names follow naming conventions;
- Diagram alt-text better reflects the image content;
- Diagram widths scale with the content body width; and
- Grammar and spelling follow American English.

docs: add inital lts doc

Ref: https://linaro.atlassian.net/browse/TFC-669

The initial LTS document was created as pdf and was maintained in a
shared folder location, to avoid pdf getting lost and trying to find
where it is we decided to have LTS details part of docs in TF-A.

This patch directly reflects the data from pdf attached to TFC-669.
Any improvements or amends to this will be done at later phases based
on LTS maintainers comments and agreements.

fix(docs): replace "ARM-TF" with "TF-A" in diagrams

Two diagrams in the documentation contained the string "ARM TF", which
is probably a remainder of the older "ARM Trusted Firmware" name.
Replace that with "TF-A", which is now the more widely known name for
Trusted Firmware.
This was done with an image editing program, by just moving the letters
around, as I didn't find any source for that image.

docs(context-mgmt): add documentation for context management library

This patch adds some documentation for the context management library.
It mainly covers the design at a higher level, with more focus on
the cold boot and warm boot entries as well as the operations
involved during context switch. Further it also includes a section
on feature enablement for individual world contexts.
