Improve the performance of the HeatMap component

When 44640 data is loaded into the component via the data source, the HeatMap's performance decreases. While debugging the source the following modules need architectural change which are:

1. When the X axis labels are calculated, it will be checked for trimming when the labels intersect with each other or the width extends the maximum width. This process takes 5 seconds for the X axis alone. The time in minimal in Y axis.

2. When the cells are rendered, the calculation for the cell position induces a slowness in the performance.

3. After the cell position calculation, it will be rendered in the razor file of the component. At this instance, the internal component used for render SVG Rect element induces a slowness in the performance.

It is necessary to resolve the aforementioned issues and improve performance to the maximum extent possible.
