Add support for using different C symbol names in //export directives
when compiling for embedded targets (enabled via -target flag).
This is for TinyGo compatibility on embedded platforms where hardware
interrupt handlers often require specific naming conventions.
Implementation:
- Add EnableExportRename() to control export rename behavior
- Add isExport parameter to initLink callback for context awareness
- Update initLinknameByDoc() to handle export rename logic:
* When isExport && enableExportRename: allow different names
* Otherwise: require name match
- Clean error handling in initLink():
* export + enableExportRename: silent return (already processed)
* export + !enableExportRename: panic with clear error message
* other cases: warning for missing linkname
Example:
//export LPSPI2_IRQHandler
func interruptLPSPI2() { ... }
The Go function is named interruptLPSPI2 but exported as
LPSPI2_IRQHandler for the hardware vector table.
