chore: Store the dimensions into dimens resource file

[hridyakrishna]

Fixed #50

Changes: The dimensions in the XML files were hardcoded. Stored them into dimens resource folder.
Changed files: activity_main.xml, delete_data.xml, insert_data.xml, layout_row_view.xml,
read_all.xml, read.data.xml, update_data.xml, dimens.xml

@hridyakrishna please follow semantic pr guidelines.

Where ever there's a padding of 0dp, instead of giving different names everytime, use a common name like padding_zero

[yashk2000]

I see that dimens are 20, 120, 5, 45, 50 mostly. Instead of creating different names for each dimension in the different files, create a common name. For example, if padding 20 is in many places, make it padding_twenty everywhere.
If it is height 20, then change it to height_20.Do the same for all other dimensions.

Try to use minimum dimensions in order to minimize the size of the app.
