Updated build options to improve performance on esp-idf 4.4/5.x

Starting with esp-idf 4.4, build options `-fno-jump-tables -fno-tree-switch-conversion` are always used. [1]

This is very bad for us because most emulators rely on switches being converted to jump tables.

This patch brings performance back to parity with 4.3.

1. https://github.com/espressif/esp-idf/releases/tag/v4.4:

> Always compile with -fno-jump-tables -fno-tree-switch-conversion by default. This could results in performance regression for code that relies heavily on this optimization. See api-guides/memory-types.rst for how to enable it for specific source files if necessary.
