[asset health] helper text for component statuses (#29117)

## Summary & Motivation
Adds various graphene metadata types so that the FE needs to build the
text based on the health status and the metadata available

tests in dagster-io/internal#14895

Messages intended to be as follows:
- Asset checks 
- `UNKNOWN` status: "No checks executed" or "X/Y checks not executed" -
with a link to the checks tab added by FE
- `WARNING` status: "X/Y checks warning" - with a link to the checks tab
added by FE
- `DEGRADED` status: "X/Y checks failed" or "X/Y checks failed, Z/Y
checks warning" - with a link to the checks tab added by FE
    - `HEALTHY` status: no message 
- `NOT_APPLICABLE` status: "No asset checks defined" - no metadata type
for this because there is no info the BE needs to pass to the FE

- Asset materialization, partitioned asset
- `UNKNOWN` status: "No materializations" - no metadata type for this
because there is no info the BE needs to pass to the FE
- `WARNING` status: "X/Y partitions missing" - with a link to the
partitions tab added by FE
- `DEGRADED` status: "X/Y partitions failed" or "X/Y partitions failed,
Z/Y partitions missing" - with a link to the partitions tab added by FE
    - `HEALTHY` status: no message 

- Asset materialization, non-partitioned asset
- `UNKNOWN` status: "No materializations" - no metadata type for this
because there is no info the BE needs to pass to the FE
    - `DEGRADED` status: "Failed in run" (run id and link added by FE)
    - `HEALTHY` status: no message
