Allow position as a fraction of resolution
...
UEFI recommends y=.382 (1 - 1 / (golden ratio)), make this the default.
Fractional position starts with a decimal point: x=.5 y=.382
Pixel offset relative to the center is set as before: x=123 y=456
If the coordinates were omitted, old default was: x=0 y=0

Fix a shim error caused by bad load options data
...
Shim expects a filename or nothing in the load options.
To avoid an error message during boot, do several things:
When creating the NVRAM entry, use empty load options. The current
string ("HackBGRT\0") was just a decoration, and it's luckily ignored
by shim because the length is odd.
When creating the entry with BCDEdit, manually fix the load options.
The load options in BCDEdit entries start with "WINDOWS\0" followed
by UINT32 version, as seen in ReactOS struct BL_WINDOWS_LOAD_OPTIONS.
The version is 1, but BCDEdit seems to be happy with a higher number.
By setting this version to 'X' (0x58), the string becomes a valid
UCS-2 file name. Update the installer so that the HackBGRT loader is
installed with this weird file name.
The reason why the load options cannot be deleted completely is that
BCDEdit will recreate the entry on next boot if it doesn't find the
entry it just tried to create.
