For a given group of heaps sharing the same capabilities, it is
best to use smaller heaps first when performing "small" allocations
to keep the bigger heaps untouched. This prevents the scenario where
a series of small allocations would crowd the bigger heaps making
any bigger allocation fail for lack of space.

In some cases we will need the dma's buffer to be aligned with specific
requirements. This MR add two helper function to split the unaligned
buffer and merge to the origin buffer. The cost is that each unaligned
buffer requires two stash buffers of spilt alignment size. And this
memory should be managed by callers.
Some component test apps do not use the "set(COMPONENTS main)" command in their
project level "CMakeLists.txt", thus leading to their builds pulling in all
ESP-IDF components.
This commit trims the build of multiple component test apps:
- Add "set(COMPONENTS main ...)" to project level "CMakeLists.txt"
- Add missing "PRIV_REQUIRES" in some "main" component "CMakeLists.txt"
Also removed repeated configuraiton options in legacy_i2c_driver/sdkconfig.ci.defaults
as they are already specified in legacy_i2c_driver/sdkconfig.defaults
On ESP32P4, becasue we need to invalidate the destination buffer,
if the buffer is not aligned to cache line, then it might break
other date structure, randomly.
There's two GDMA groups on ESP32P4, one is connected to AHB bus,
and another one is connected AXI bus.
We now have two seperate APIs for allocating DMA channels,
depends on the bus type.
1. add check in the gdma driver, to prevent multiple channels connecting
to the same peripheral
2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP
targets (e.g. esp32c3/s3). We should search for a free one when
install async memcpy driver.
