Add support for CIDR notation in RemoteIpFilter(#632)

[ABin-Huang]

CIDR Rule Storage Logic:

A dedicated netMaskSet storage mechanism is introduced to store the parsed CIDR network segment rules for
internal proxies and trusted proxies, providing data support for subsequent IP verification.

Proxy IP Verification Logic:

When verifying an internal proxy IP, it first checks whether the IP conforms to the original regular expression format. If not, it
further verifies whether the IP falls within the stored CIDR network segments of internal proxies.
When verifying a trusted proxy IP, it also first checks whether the IP matches the original regular expression format. If not, it
further confirms whether the IP is within the stored CIDR network segments of trusted proxies.
