With MINIMAL_BUILD enabled, menuconfig will only display configuration
options for components included in the build through main component
dependencies. This means that configuration options for excluded
components will not appear in menuconfig. This might be confusing, as
most examples currently do not use a trimmed build, and all components
detected by the build system are available in menuconfig, even if their
configuration has no effect because the components may not be linked or
used. Adding a note in the components menu of menuconfig could help
users realize they need to add a component to the main component
requirements to see its configuration options. Unfortunately, Kconfig
does not support multiline comments, so there are three separate
comments intended to adequately describe the potentially missing
component configurations.

Include a description of the MINIMAL_BUILD property, which serves as a
shortcut for set(COMPONENTS main). Additionally, add a note to the
relevant components indicating that they must be included in the build
to allow for their configuration.

The test_build_cmake_library_psram_workaround verifies that the
mfix-esp32-psram-cache-issue flag is applied to all compile commands in
compile_commands.json when CONFIG_SPIRAM_CACHE_WORKAROUND=y. Although
the import_lib does not need the esp_psram component, this test does. To
avoid adding the esp_psram dependency to the import_lib, disable
MINIMAL_BUILD for this test by explicitly setting the COMPONENTS
variable.

The check_public_headers.py script does not function well with
MINIMAL_BUILD enabled, as some headers from excluded components may be
missing. While it might be possible to address this issue with
exclusions, it is likely more effective and provides more coverage to
include all components, not just those required by the blink example.
Therefore, MINIMAL_BUILD has been disabled for this test, ensuring that
all registered components are included in the build. If defined, the
COMPONENTS variable takes precedence over the MINIMAL_BUILD property, so
setting "-DCOMPONENTS=" overrides the MINIMAL_BUILD property.

Currently, several example dependencies rely on the fact that all
registered components are added to the build, along with components
specified in common requirements. This results in longer build times
because even unused components must be built. Switch all examples to use
idf_minimal_build to compile only the components actually required by
the example.

Introduce a MINIMAL_BUILD property to streamline the build process by
including only the main component and its direct and indirect
dependencies. This serves as a convenient shortcut for using
set(COMPONENTS main). The MINIMAL_BUILD build property is ignored if the
COMPONENTS variable is defined, as COMPONENTS takes precedence.
To enable a minimal build, add "idf_build_set_property(MINIMAL_BUILD ON)"
to the project's CMake configuration.

Currently, several examples do not explicitly state their component
dependencies, relying instead on the default behavior that includes all
registered components and commonly required ones in the build.
Explicitly adding component dependencies can reduce build time when
set(COMPONENTS main) is used.

The object files are compiled simultaneously, which can result in
several error messages about missing headers. The current regex used to
find missing headers in the compiler's output employs a greedy search,
potentially capturing multiple error messages from different compilation
units. This can cause bug reports where the original component cannot be
identified. Strengthen the regex to ensure it only processes the first
reported error.
