Fix(XUI): Resolve parsing warnings for Fixed Environment editor widgets

Problem:
Opening the Fixed Environment floater generated three distinct XUI parsing warnings in the logs:
- Failed to parse parameter "decimal_digits." in xy_vector.xml
- Failed to parse parameter "user_resize." in xy_vector.xml
- Failed to parse parameter "logarithmic." in panel_settings_sky_clouds.xml

Cause:
These attributes were either not recognized/utilized by the underlying C++ widget implementations ('decimal_digits', 'user_resize' in LLXYVector) or were using an incorrect value ('logarithmic="1"' instead of a boolean 'true'/'false' in LLSliderCtrl).

Solution:
This commit addresses these three warnings:
- Removed the extraneous 'decimal_digits' and 'user_resize' attributes from the definition of the 'xyvector' widget in xy_vector.xml.
- Corrected the 'logarithmic' attribute value from "1" to "true" for the 'cloud_scroll_xy' slider in panel_settings_sky_clouds.xml.

Result:
Eliminates these specific parsing warnings from the logs when the Fixed Environment floater is opened.

Testing:
- Launch viewer.
- Open World -> Environment Editor -> My Environments.
- Select a sky setting and click Edit (or create a New one).
- Observe the logs upon the Fixed Environment floater opening.
- Verify the absence of the 'decimal_digits', 'user_resize' (from xy_vector.xml), and 'logarithmic' (from panel_settings_sky_clouds.xml) parsing warnings.
