Add ETH_800GBASE_2XLR4 and ETH_800GBASE_2XPLR4 PMD types

[cpubob]

Description

This Pull Request proposes the addition of two new 800G Ethernet Physical Medium Dependent (PMD) types to the openconfig-transport-types.yang module.
These additions are made under the ETHERNET_PMD_TYPE base identity to support newer 800G transceiver compliance codes:

• ETH_800GBASE_2XLR4: Ethernet compliance code for 800GBASE_2XLR4 (typically 2x400G LR4).
• ETH_800GBASE_2XPLR4: Ethernet compliance code for 800GBASE_2XPLR4 (typically 2x400G PLR4).

Rationale

As 800G optics deploy, these PMD types are increasingly required to model interfaces using dual-carrier/breakout 400G interfaces packaged as a single 800G transceiver (2x400G LR4/PLR4). Adding them to the standard public models ensures vendor-neutral consistency.

YANG Changes

• Module: release/models/optical-transport/openconfig-transport-types.yang
• Added identity ETH_800GBASE_2XLR4
• Added identity ETH_800GBASE_2XPLR4
• Bumped openconfig-version to 1.5.0 (minor version bump for backward-compatible additions).
• Added revision "2026-06-09" with description.

Compatibility

This change is fully backward-compatible as it only introduces new identities.
