Convert UART configuration PCDs from FixedPcd to dynamic Pcd to enable
runtime modification of serial port parameters.
Changes made:
- Replace FixedPcdGet64/FixedPcdGet8 calls with PcdGet64/PcdGet8 for:
* PcdUartDefaultBaudRate
* PcdUartDefaultParity
* PcdUartDefaultDataBits
* PcdUartDefaultStopBits
- Update INF file to declare these PCDs under [Pcd].
