Add call to HdwPortInitialize() when instantiating logger in DXE (#411)

## Description

This change adds a call to AdvancedLoggerHdwPortInitialize() when the
advanced logger is created in the DxeCoreAdvancedLoggerLibConstructor().
Previously, hardware port was only initalized in AdvancedLoggerGetInfo()
if the logging info structure was present at a fixed location or in a
HOB; this would cause writes to the hardware port to potentially fail in
the path where the logger is not initialized until the Constructor is
called.

- [x] Impacts functionality?
- AdvancedLoggerHdwPortInitialize() is now called in the
DxeCoreAdvancedLoggerLibConstructor if the logger is instantiated there.
- [ ] Impacts security?
- [ ] Breaking change?
- [ ] Includes tests?
- [ ] Includes documentation?

## How This Was Tested

Verified on a platform where this was not working due to missing HdwPort
initialization; verified after this patch that it works as expected.
