Add a -P option to fs_config_generate that allows us to filter on
a comma separated partition whitelist or minus prefixed -blacklist.
A partition is defined as accessible as <partition>/ or
system/<partition>/.
No change for legacy, where no -P flag is specified.
For system.img, but not vendor, oem or odm file references:
fs_config_generate -P -vendor,-oem,-odm
For vendor.img file references:
fs_config_generate -P vendor
For oem.img file references:
fs_config_generate -P oem
For odm.img file references:
fs_config_generate -P odm
Add and fortify tests for each of these cases.
SideEffects: none
Test: gTest host fs_config-unit-test

fs_config_generate_$(TARGET_DEVICE) is built based off the content
of $(TARGET_ANDROID_FILESYSTEM_CONFIG_H). We also add the rules
fs_config_dirs and fs_config_file to utilize this command
for target contents:
fs_config_generate_$(TARGET_DEVICE) -D -o system/etc/fs_config_dir
fs_config_generate_$(TARGET_DEVICE) -F -o system/etc/fs_config_file
In order to use this feature, one must have the fs_config_dirs and
fs_config_files in the $(PRODUCT_PACKAGES) list defined in the
device make files in $(TARGET_DEVICE_DIR). And either an
android_filesystem_config.h file in that directory, or define a
path in TARGET_ANDROID_FILESYSTEM_CONFIG_H to point to one.
