The Linux emulator had no working audio output: the speaker endpoint had a
NULL driver (streams returned -ENODEV). This adds an SDL2 audio playback
driver for the output path.

Add oversampling for each target:
- MD-3x0, MD-UV3x0, MD-9600, DM-1701, CS7000: 8 (64 kHz)
- CS7000-PLUS: 6 (48 kHz, LPTIM3 cannot trigger ADC at 64 kHz)
- All other targets default to 1 via #ifndef guard (no oversampling)

Replace the platform-specific #ifdef chain for micGain in audio_codec.c
with a CONFIG_MIC_GAIN macro defined in each target's hwconfig.h. This
removes code forking in the codec and makes mic gain a per-device
hardware configuration parameter.

platform_getMicLevel() now samples data from the ADC
configured for the hardware VOX circuit instead of the
microphone input ADC, which has a fixed 1.65V bias and
is unsuitable for checking mic level.
Normalization is performed specific to the characteristics
of the hardware VOX circuit. Values are output between 0-255
to ensure API compatibility.

The CS7000P schematic indicates the hardware VOX circuit
is connected to PC4 on the STM32H7. The pinmap.h file has
been updated to reflect this. The existing assignment of
AIN_VBAT to GPIOC,4 looks like a holdover from another
devices pinmap.
Create a new ADC channel, ADC_VOX_CH
assigned to the ADC matching the GPIO pin that
the VOX circuit is connected to.

This change removes the old copyright header from project sources and
replaces it with a new simplified SPDX-compliant header. Note that files
that were missing the header but reasonably understood to be licensed
according to the root license were not corrected.

Update meson and cmake config to only include openrtx and platform paths.
Update files to use <..> for system and external libraries, ".." for
project files and new relative paths as necessary.
Did not attempt to fix areas where includes that should be <..> were
previously ".."
Inspired by #96, closes#359.
