* feat(gw): response type histogram metrics
- response-type agnostic firstContentBlockGetMetric which counts the
latency til the first content block.
- car/block/file/gen-dir-index duration histogram metrics that show how
long each response type takes
* docs: improve metrics descriptions
* feat: more gw histogram buckets
0.05, 0.1, 0.25, 0.5, 1, 2, 5, 10, 30, 60 secs

* feat: serveRawBlock implements ?format=block
* feat: serveCar implements ?format=car
* feat(gw): ?format= or Accept HTTP header
- extracted file-like content type responses to separate .go files
- Accept HTTP header with support for application/vnd.ipld.* types
* fix: use .bin for raw block content-disposition
.raw may be handled by something, depending on OS, and .bin
seems to be universally "binary file" across all systems:

* refactor: gateway_handler_unixfs.go
- Moved UnixFS response handling to gateway_handler_unixfs*.go files.
- Removed support for X-Ipfs-Gateway-Prefix (Closes#7702)
* refactor: prefix cleanup and readable paths
- removed dead code after X-Ipfs-Gateway-Prefix is gone
(https://github.com/ipfs/go-ipfs/issues/7702)
- escaped special characters in content paths returned with http.Error
making them both safer and easier to reason about (e.g. when invisible
whitespace Unicode is used)
