abuthahirm 5acaac4f32 NetworkPkg/Ip4Dxe: Reject IPv4 addresses ending with dot 
Issue: UI accepts invalid IPv4 addresses ending with a dot in the
IPv4 Network Configuration page. Examples:
- Local IP Address: 192.168.1.10.
- Subnet Mask: 255.255.255.0.
- Gateway: 2.2.2.2.
- DNS Servers: 1.1.1.1.

Root Cause:
The function Ip4Config2StrToIp converts user-entered IPv4 strings
into numbers. When an address ending with a dot like '1.1.1.1.' is
entered, the code skips over the 4th dot, reaches the string's null
terminator, and incorrectly treats it as valid.

Fix:
Refactor Ip4Config2StrToIp to be a thin wrapper around the existing
BaseLib StrToIpv4Address() helper. After parsing, the EndPointer is
checked to ensure the entire string was consumed (i.e. EndPointer
points to the null terminator). Any trailing characters, including
a trailing dot, cause EFI_INVALID_PARAMETER to be returned.
