feat(linux): Enable XDP documentation for supported platforms

Add XDP documentation support to the following SoC platforms by
including Network/XDP.rst in their device-specific table of contents:

- AM62AX (am62axx_sk-fs)
- AM62PX (am62pxx_sk-fs)
- AM62X (am62xx_sk-fs)
- J7200 (j7200-evm)
- J721E (j721e-idk-gw)
- J722S (j722s_evm-fs)

Note: AM64X (am64xx-evm, am64xx-hsevm) already has XDP support from
the initial commit.

This ensures that users of these platforms can access the consolidated
XDP documentation covering Native XDP, Generic XDP, and Zero-copy modes.
