Backport the focused port-resolution behavior from upstream PR #1950 to the 202603 branch. Resolve SAI ports from their lane list and SONiC port_config.ini so boot-time admin state, MTU, and speed can be applied before hostif creation. Signed-off-by: Jana Palanisamy (janapal) <janapal@cisco.com>

Summary
Backports focused VPP port-resolution support from sonic-net/sonic-sairedis#1950 to the
202603branch.This resolves SAI ports from their lane configuration and
port_config.inibefore hostif creation, allowing boot-time admin state, MTU, and speed configuration to be applied correctly.Also exposes the VPP interface-index lookup required by the backported implementation.
Testing
TC1 - PASS: Matched 1G on Local and Peer devices; link came up at 1G.
TC2 - PASS: Matched 10G on both devices; link came up at 10G.
TC3 - PASS: Local 10G and Peer 1G mismatch; both links stayed down.
TC4 - PASS: Local 1G and Peer 10G mismatch; both links stayed down.
TC5 - PASS: Verified boot-time speed replay from 10G to 1G with matched peer.
TC6 - PASS: Verified boot-time speed replay from 1G to 10G with matched peer.
TC7 - PASS: Verified CLI speed change, config save, and reboot persistence.
TC8 - PASS: Regenerated CONFIG_DB from port_config.ini; configured speed was applied during boot.
TC9 - PASS: CONFIG_DB, APPL_DB, STATE_DB, ethtool, VPP, and SAI reflected the expected speed.
TC10 - PASS: Key containers remained running with zero restarts and no failed systemd units.
