Add namedpipereceiver (open-telemetry#29320)

**Description:**

This adds a new receiver that reads from a named pipe, using the
previously created namedpipeinput stanza operator (open-telemetry#28841). Because that
operator does the majority of the work, this is mostly boilerplate + a
few tests to confirm that it works e2e.

Link to tracking Issue: open-telemetry#27234

**Testing:**

Added a few tests, loading the config, and actually creating a receiver
to verify that it can read logs from the pipe.

**Documentation:**

None, yet.

/cc @djaglowski - where should I add docs for this if any?

+
+This receiver supports opening a Unix Named Pipe (aka FIFO), and reading logs from it.
+
+## Prerequisites
+
+Named pipes are only supported on Unix operating systems.
+
+
+## Configuration
+
+The following settings are required:
+
+- `path`: The path to open the named pipe at.
+
+The following settings are optional:
+
+- `mode`: The mode bits to set on the opened pipe (default: 666)
+
+## Example Configuration
+
+```yaml
+receivers:
+  namedpipe:
+    path: /tmp/pipe
+    mode: 0600
+```
