Release 1.78.0

[Compare
Source](https://redirect.github.com/grpc/grpc-go/compare/v1.77.0...v1.78.0)

##### Behavior Changes

- client: Reject target URLs containing unbracketed colons in the
hostname in Go version 1.26+.
([#&#8203;8716](https://redirect.github.com/grpc/grpc-go/issues/8716))
  - Special Thanks: [@&#8203;neild](https://redirect.github.com/neild)

##### New Features

- stats/otel: Add backend service label to wrr metrics as part of A89.
([#&#8203;8737](https://redirect.github.com/grpc/grpc-go/issues/8737))
- stats/otel: Add subchannel metrics (without the disconnection reason)
to eventually replace the pickfirst metrics.
([#&#8203;8738](https://redirect.github.com/grpc/grpc-go/issues/8738))
- client: Wait for all pending goroutines to complete when closing a
graceful switch balancer.
([#&#8203;8746](https://redirect.github.com/grpc/grpc-go/issues/8746))
  - Special Thanks: [@&#8203;twz123](https://redirect.github.com/twz123)

##### Bug Fixes

- transport/client : Return status code `Unknown` on malformed
grpc-status.
([#&#8203;8735](https://redirect.github.com/grpc/grpc-go/issues/8735))
- client: Add `experimental.AcceptCompressors` so callers can restrict
the `grpc-accept-encoding` header advertised for a call.
([#&#8203;8718](https://redirect.github.com/grpc/grpc-go/issues/8718))
- Special Thanks:
[@&#8203;iblancasa](https://redirect.github.com/iblancasa)
- xds: Fix a bug in `StringMatcher` where regexes would match
incorrectly when ignore\_case is set to true.
([#&#8203;8723](https://redirect.github.com/grpc/grpc-go/issues/8723))
- xds/resolver:
- Drop previous route resources and report an error when no matching
virtual host is found.
- Only log LDS/RDS configuration errors following a successful update
and retain the last valid resource to prevent transient failures.
([#&#8203;8711](https://redirect.github.com/grpc/grpc-go/issues/8711))
- client:
- Change connectivity state to CONNECTING when creating the name
resolver (as part of exiting IDLE).
- Change connectivity state to TRANSIENT\_FAILURE if name resolver
creation fails (as part of exiting IDLE).
- Change connectivity state to IDLE after idle timeout expires even when
current state is TRANSIENT\_FAILURE.
- Fix a bug that resulted in `OnFinish` call option not being invoked
for RPCs where stream creation failed.
([#&#8203;8710](https://redirect.github.com/grpc/grpc-go/issues/8710))
- xdsclient: Fix a race in the xdsClient that could lead to
resource-not-found errors.
([#&#8203;8627](https://redirect.github.com/grpc/grpc-go/issues/8627))

##### Performance Improvements

- mem: Round up to nearest 4KiB for pool allocations larger than 1MiB.
([#&#8203;8705](https://redirect.github.com/grpc/grpc-go/issues/8705))
  - Special Thanks: [@&#8203;cjc25](https://redirect.github.com/cjc25)
