Make XDP eBPF enabled by default

[saxena-anurag]

Currently XDP does not register as eBPF extension provider by default, and we need to set XdpEbpfEnabled reg key and restart XDP driver to enable the feature. This issue is to enable it by default so that an extra step is avoided.

Until this issue is resolved, please add the below instruction to the README file:

1. 'reg.exe add HKLM\SYSTEM\CurrentControlSet\Services\xdp\Parameters /v XdpEbpfEnabled /d 1 /t REG_DWORD /f'

2. Version compatibility:
   ebpf-for-windows v0.14.1 msi version with xdp-for-windows v1.1.0+c10f37fa
