[202412][Broadcom] Upgrade Broadcom xgs SAI version to 13.2.1.38

[Gfrom2016]

Why I did it

Bump Broadcom xgs SAI version from 13.2.1.37 to 13.2.1.38. Includes:

• 13.2.1.38: Package bcm78907_a0 (TH5) techsupport .soc files into libsaibcm so they install at /etc/bcm/techsupport/bcm78907_a0/base/ on the device and can be invoked via bcmcmd rcload from the show techsupport flow on TH5 platforms (e.g. Arista 7060X6). Tracking: aristanetworks/sonic-qual.msft#1255, BCM CSP CS00012459017.
