newlib: fix register used for DPORT/RTC bug workaround
While there was no register at DR_REG_FRC_TIMER_BASE + 0x60, due to
peripheral address space wraparound this write actually affected one of
FRC2 registers, which is used by WiFi stack to implement legacy
ets_timer APIs.
This change uses FRC_TIMER_LOAD_REG(0) instead, which can be set to
known value safely.

Merge branch 'feature/parse_unit_test_cases_from_test_files' into 'master'
Parse unit test cases from test files
As of now, we need to sync three different places when adding new unit test cases. The plan is to add a python script in tools/unit-test-app. This script would parse unit test cases from the C files with tests and generate the needed YAML files in components/idf_test/unit_test. CI would run this script in build stage to create the files and unit-test stage would use the generated files to run tests.
To get the needed test metadata, we need to add some more tags in the test case functions. For example:
```
TEST_CASE("SYS_LIB_0102 test time functions", "[stdlib][fails][env=UT_T1_APC]")
{
//...
}
```
Reason for this kind of implementation is that we need the YAML files for generating documents.

time: workaround for FRC_TIMER_INT_REG write issue
In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus.
Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.

newlib: change definition of assert for release builds
One common pattern of using assert function looks as follows:
int ret = do_foo();
assert(ret == 0); // which reads as: “do_foo should never fail here, by design”
The problem with such code is that if ‘assert’ is removed by the preprocessor in release build,
variable ret is no longer used, and the compiler issues a warning about this.
Changing assert definition in the way done here make the variable used, from language syntax perspective.
Semantically, the variable is still unused at run time (as sizeof can be evaluated at compile time), so the compiler
can optimize things away if possible.

spi_flash: define spi_flash_guard_{start,stop} with IRAM_ATTR
These functions are marked as inline and are called from functions which are in IRAM.
In release (-Os) builds, the compiler may decide not to inline these functions.
Placing these functions into IRAM explicitly works around this.

Merge branch 'bugfix/deep_sleep' into 'master'
deep sleep related fixes
A few fixes for deep sleep behavior:
- Fix a regression that deep sleep stub crashed if `ESP32_DEEP_SLEEP_WAKEUP_DELAY` option was enabled — the stub called `ets_update_cpu_frequency`, which was recently redefined to be an IRAM function, rather than a ROM one. Fixed by restoring the ROM definition as `ets_update_cpu_frequency_rom`, and using that in the deep sleep stub.
- By default, don't power down RTC_SLOW_MEM if there is any data in .rtc.data or .rtc.bss sections. This provides better out-of-the box experience, as variables attributed to .rtc.data are actually preserved during deep sleep.
- Store boot time in RTC_STORE registers instead of using a variable with RTC_DATA_ATTR. This allows RTC_SLOW_MEM to be powered down in deep sleep if no variables with RTC_DATA_ATTR are present in the program.
