feat(esp-box): Update implementation

[finger563]

Description

• Break up implementation into different source files
• Update audio interface to allow configuration of audio task

Motivation and Context

• Previously, we had manually marked some functions as IRAM_ATTR, but this removes control from application developers who may not need those to be IRAM_ATTR. Application code can now use linker files instead to place the functions into IRAM if they choose to.
• Previously we had hard-coded the audio task at a specific Task::Config. This PR keeps that as the default, but enables application code to override it if they choose to.

How has this been tested?

• Building and running esp-box/example on a ESP32-S3-BOX-3
• Building and running within esp-cpp/esp-box-emu which uses this component.

Screenshots (if appropriate, e.g. schematic, board, console logs, lab pictures):
