Add template simulation API for simulating template composition
This adds an API for simulating template composition with or without an index template.
It looks like:
```
POST /_index_template/_simulate/my-template
```
To simulate a template named `my-template` that already exists, or, to simulate a template that does
not already exist:
```
POST /_index_template/_simulate
{
"index_patterns": ["my-index"]
"composed_of": ["ct1", "ct2"],
}
```
This is related to elastic#55686, which adds an API to simulate composition based on an index name (hence
the `_simulate_index` vs `_simulate`).
This commit also adds reference documentation for both simulation APIs.
