newlib: implement fsync for the case of CONFIG_VFS_SUPPORT_IO=0
This feature allows calling fsync even if the vfs component is not
used.
The second part of the commit adds an fsync call in the panic test app
enabling it to be used over usb-serial-jtag.

newlib: fix return value of no-VFS _read_r if nothing received
'read' function should return 0 when encountering an end of file. When
newlib calls read and sees EOF returned, it assumes that this
condition is permanent and never calls 'read' for this file again
(unless the read pointer is moved using fseek).
The correct behavior in case no characters were received over UART is
to return -1. In this case newlib will retry reading from file on next
call to fread, fgetc or another function which calls __srefill_r.

ccda990ce5 newlib: set errno in the explicitly provided reent structure
Since these functions receive the pointer to reent structure, they
should set errno in it rather than using thread-local errno.

This didn't cause practical issues because console functions in IDF
are only called from threads, and in that case 'r' is a pointer to
the thread-local structure, so &errno is the same thing as
&__errno_r(r). Still, fixing this for consistency.

5da66d1d39 newlib: implement _fstat_r stub for console
When CONFIG_VFS_SUPPORT_IO is disabled, _read_r and _write_r
implementations in syscalls.c are used to provide console I/O via
esp_rom_uart_tx_one_char/esp_rom_uart_rx_one_char.

When newlib opens a (FILE*) stream, it calls fstat to check if the
underlying file is character-oriented. In this case, it configures the
stream to use line buffering. Otherwise (or if fstat fails) the stream
is opened as block buffered.

Since fstat wasn't provided, stdin/stdout/stderr streams got opened in
block buffered mode. For console, we need line buffered output so that
the stream buffer is flushed each time a complete line (ending with
'\n') is sent to stdout or stderr.

Fix by implementing _fstat_r stub, setting st->st_mdoe=S_IFCHR.

420aef1ffe Updates for riscv support
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
  longer signed/unsigned int).

Changes come from internal branch commit a6723fc
