OvmfPkg/PlatformBootManagerLib: rejuvenate old-style function comments
The old-style "Routine Description: ..." comments use the leftmost column and are placed between the parameter list and the function body. Therefore they cause git-diff to produce bogus hunk headers that fail to name the function being patched. Convert these comment blocks to the current edk2 style. While at it, clean them up too. For PlatformBootManagerBeforeConsole() and PlatformBootManagerAfterConsole(), copy the descriptions from the call sites in "MdeModulePkg/Universal/BdsDxe/BdsEntry.c". They are more detailed than the comments in the lib class header "MdeModulePkg/Include/Library/PlatformBootManagerLib.h"; ArmVirtPkg already uses these comments. No functional changes.
