ROU-10780: fix Google Maps custom markers with scaled sizes

[gnbm]

This PR is to fix Google Maps custom markers with scaled sizes.

What was happening

• Setting custom markers using URL and icon size being set, didn’t have the right behaviour (regression from v1.6.6) and the markers didn't appear properly:

What was done

• The Google Maps marker API on the OutSystems MAps implementation used in the method _setIcon is an object with an attribute size when it should use scaledSize.
• Also, the Google Maps API got changed and requires the attributes anchor and, for readability (not mandatory in this case), also the origin so the icon gets properly scaled.

Test Steps

1. Create a test screen with two Maps using custom markers - one setting up the IconSize and the other without this structure filled in
2. Check that for both Maps we can properly see the Markers we just defined on the low code implementation

Screenshots

Checklist

• tested locally
• documented the code
• clean all warnings and errors of eslint
• requires changes in OutSystems (if so, provide a module with changes)
• requires new sample page in OutSystems (if so, provide a module with changes)
