oliverpoolandEarl Warren 31ad7c9353 blob: GetBlobContent: reduce allocations (#8223)
See #8222 for context.

## git.Blob.NewTruncatedReader

This introduce a new `NewTruncatedReader` method to return a blob-reader which silently truncates when the limit is reached (io.EOF will be returned).
Since the actual size is also returned `GetBlobContent` can pre-allocate a `[]byte` of the full-size (min of the asked size and the actual size) and call `io.ReadFull(rc, buf)` (instead of `util.ReadWithLimit(dataRc, int(limit))` which is convoluted and not used anywhere else).

### Tests

- I added test coverage for Go changes...
  - [x] in their respective `*_test.go` for unit tests.

### Documentation

- [x] I did not document these changes and I do not expect someone else to do it.

### Release notes

- [x] I do not want this change to show in the release notes.
