Add testcases to PerformanceTests/CSS to test changing style in trees of different depth

This CL adds a utils file that allows us to create a DOM tree of
varying depth and branch factor.

We use this file to create trees with:
1. Shallow tree (depth=2) with high branching factor(10)
2. Deep tree (depth=10) with small branching factor(2)

We then change the style of all elements in the tree and benchmark the
number of runs done in a second. This allows us to set up a benchmark
for style manipulation as a benchmark is not currently present.

Add testcases to PerformanceTests/CSS to test changing style using selectors

This CL amends the utils file to add a DOM tree generator function.

We then change the style of all elements in the tree and benchmark the
time spent. This allows us to set up a benchmark for style manipulation
done using selectors.

Add testcases to PerformanceTests/CSS to test changing style using selectors

We then change the style of all elements in the tree and benchmark the
time spent. This allows us to set up a benchmark for style manipulation
done using selectors.

This adds test to apply pseudo selectors on:
1. Children of elements
2. Grand children of elements
3. All elements (universal selector)
4. Checking for partrial match for an attribute
