And leave all intermediate file in apps/wasm,
such as .map file, entry object etc used in
wasm module build.

Try to follow current NuttX's toolchain parttern:
Wasm.mk: Provide target rule for building wasm module
WASI-SDK.defs: Provide compile flags for building

when a program has multiple MAINSRC for incremental compilation,
the PROGNAME of the compiled file may generate errors
-------------------- compile definition error ---------------------
cc -c -g CFLAGS INCLUDEDIR -Dmain=funA_main funB.c -o funB.c.path.o
^^^^ ^^^^^^ ^^^^
-------------------------------------------------------------------
use the MAINOBJ:PROGNAME mapping variable to define the main entry name

wasm clang can't find math.h if using libm from toolchain.
It's OK to using math.h from NuttX since only declaration is needed for wasm build.

For example, before this patch, object file is like:
```
apps/examples/hello/hello_main.wo
```
With this patch, it will be:
```
apps/examples/hello/hello_main.c.home.huang.Work.nx.apps.examples.hello.wo
'''
Follow the native build:
'''
apps/examples/hello/hello_main.c.home.huang.Work.nx.apps.examples.hello.o
```
