[DOCS] Reorganize, rewrite and add examples to analysis topics

[kat257]

As part of the larger effort to update and improve Elasticsearch docs, the Analysis section is in need of a revamp. Relevant issues: the topics vary in depth and completeness; some have dated examples or examples that are not consistent; chunking may need to be removed or added; and the organization is arbitrary and does not always show the relationship between one topic and another.

To make these changes, docs covered by this issue will incorporate a revised, standardized structure. For example, in token filters, I'll add examples, configuration parameters, and customization options, and replace circular definitions such as "NGram Token Filter: A token filter of type ngram" with a complete definition and explanation about when the user would expect to employ that filter.

Proposed structure:

1. Title (Level 2): Definition and explanation of topic
2. Example (Level 3): Vanilla example and output
3. Configure parameters (Level 3): Parameters available with descriptions
4. Customize (Level 3): How to customize
5. Example (Level 4): Customize example and output

PRs will be revised as I work through the topics. Some PRs may include more than one topic when changes are small and comparable across topics.
