This commit enables BMP180 suport for ESP32.
...
As ESP32 has 2 I2C interfaces and BMP180 is a I2C sensor, the criterias to use BMP180 in I2C0 or I2C1 are:
1- First, bring-up routines search for BMP180 in I2C0.
If BMP180 is found in I2C0, then /dev/press0 is created.
2- If BMP180 cannot be registered in I2C0, bring-up routines search for it in I2C1.
If BMP180 is found in I2C1, then /dev/press0 is created.
It means only one BMP180 could be suported in Nuttx. In my tests I've observed
that BMP180 example application doesn't seem to work with /dev/press1 BMP180 device,
therefore even BMP180 is found in I2C1, it'll be registered as /dev/press0 device.

This commit implements I2C support for ESP32 (wrover kit).
...
It was missing and it wasn't possible to enable I2C (0 and/or 1)
before this fix.
To sum up, this fix implements a I2C register function in ESP32
bring-up routines (esp32_bringup.c) and call if for I2C0 and/or
I2C1 during ESP32 bringup (these function callings are conditioned
by CONFIG_ESP32_I2C (to check if I2C support has been configured),
CONFIG_ESP32_I2C0 (to check if I2C0 support has been configured)
and CONFIG_ESP32_I2C1 (to check if I2C1 support has been configured).
Once this fix is implemented, /dev/i2c0 and/or /dev/i2c1 interfaces
become available and work fine.

...
regards to the data used by the ROM.
Static alloaction sections should end at the begining of the ROM data.
The rest of memory (End of ROM data --> End of DRAM) is added to the
heap.

make/expression: improving up asm/C/C++ compile times
...
In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.
For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}
CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------
All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:
tools/Config.mk:
--------------------------------------------------------------------------------
define COMPILE
@echo "CC: $1"
$(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------
All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.
So the we recommand to change the syntax of assignment
From
Recursive (=)
To
Simple (:=)
In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.

CI: Store artifacts durring build
...
Add new option -A is added to tools/testbuild.sh that will take the
created build executable and store it in a folder for the config
that generated it under $ARTIFACTDIR which can be set via an
environment variable or defaulted to $(TOPDIR)/buildartifacts
This is also helpful for local testing because you can now run
tools/testbuild.sh -A sim.dat and have all of the simulation
targets generated without having to rebuild along the way.
In the GitHub Actions workflow the artifacs are uploaded
two two bundles one for macOS and one for Linux

esp32_flash.ld: Avoid having too many sections
...
Fixes an issue I saw when trying libcxx.
esptool.py has a limit of 16 sections.
It complains like:
A fatal error occurred: Invalid segment count 23 (max 16).
Usually this indicates a linker script problem.
