use CI dependencies could waste a lot bandwidth for target test jobs, as
example binary artifacts are very large. Now we will parse required
artifacts first, then use API to download required files in artifacts.
Tests for external flash chips used to controlled by macros, one bin for
one chip. And tests are done manually. This commit refactored the test
so that all 3 chips can all run in single test.
The workaround for PSRAM that will occupy an SPI bus is enabled only when:
1. used on 32MBit ver 0 PSRAM.
2. work at 80MHz.
The test used to only check 32MBit by the config option, but for PSRAM
on Wrover-B module seems to use a newer version of 32MBit PSRAM. So it
expects the workaround to be enabled, but actually not.
This commit split the unit test into two parts:
1. check all SPI buses are available, for all configs except psram_hspi
and psram_vspi, run on regular runners (including Wrover and Wrover-B).
a hidden option is enabled so that the compiler knows it's not building
psram_hspi or psram_vspi.
2. check the specified bus are acquired, for config psram_hspi and
psram_vspi. This only run on special runner (legacy Wrover module).
Replace the outdated build_installer.sh with the steps used in CI,
call build_installer.sh from CI. Move the signing part into the new
script, sign_installer.sh.
